Ecu Tuners Reviews Best Brands

The table above is a shortlist, not a fitment guarantee. Confirm year, make, model, engine, transmission and PCM strategy in the maker’s fitment tool, and order by part number, before buying any tuner here. Related performance and truck guides live under Performance Modification and the ECU Tuners archive.

How to choose an ECU tuner

Fitment first, brand second

Confirm year, make, model, engine, transmission and PCM strategy, then order by part number. The SCT X4 alone is three parts: 7015 for Ford, 7416 for GM and 7215 for Chrysler, Dodge, Jeep and Ram. The same split applies to the DiabloSport i3 and the Superchips F5. A tuner that does not list your exact application is not a maybe; it is the wrong part number, and no headline gain makes it the right one.

Flash tuner or inline module

Every pick in this guide except the category note below is a flash programmer: it rewrites the factory calibration through the OBD-II port and can restore the stock tune. Inline modules plug into factory connectors and adjust signals without flashing the PCM, which suits readers who want on-the-fly level changes or who do not want a PCM flash. Inline modules are just as application-specific, and no inline module is a buy pick here because no inline-module ASIN was verified.

Preloaded tunes or custom tunes

Preloaded tunes suit stock or lightly modified vehicles, and they only mean what they say on the octane you actually use, since several gains in this guide are premium-fuel figures. Custom tunes suit modified vehicles with intake, exhaust, head, cam or forced-induction changes, but they need a dealer, and newer encrypted PCMs may require custom tuning even where older years had preloaded coverage. Buy the path your vehicle and your modifications actually need.

Honest gains, not headline gains

Treat every gain as maker-claimed, marked up to, and tied to one vehicle, one fuel and one tune level. Tow tunes are not performance tunes, and using a performance or extreme level for heavy towing is not supported by the level descriptions. Diesel tow, performance and extreme levels carry different rated gains, so never quote a family-maximum figure as your expected gain, and never carry a gain from one make to another.

Monitoring and diagnostics

Decide whether you need a permanent monitor or only a flash-and-remove handheld. The Trinity 2, the Evolution CTS family and the Bully Dog GT Platinum give you gauges in the cab every day; the inTune i3, the X4 and the Flashpaq F5 flash the vehicle and come out. Check DTC read and clear, data logging, gauge parameters and whether a separate monitor is still needed, because a handheld without a display cannot do a monitor’s daily job.

Emissions legality for your state

Check the exact variant’s status, never the brand’s reputation. Fifty-state-legal versions exist for some families, including the Bully Dog GT Gas 40410 and the Trinity 2 EX Standard under CARB E.O. D-770, while Platinum and non-CARB versions of the same family are stated as not 50-state legal. Several listings state they are not legal for sale or use in California on pollution-controlled vehicles, so reproduce the variant-specific warning and never claim a tuner deletes emissions equipment.

ECU tuners by budget

No prices are printed in this guide. Tiers describe what the device does, not what it costs.

Types of ECU tuners

Inline modules appear in this guide only as a category explainer. The Edge Pulsar family is an example of the category, not a buy pick, because no Pulsar ASIN was verified in the research for this article.

Chrysler Dodge Ram Pick: DiabloSport inTune i3 Platinum 8345

Chrysler Dodge Ram Pick

Why the DiabloSport inTune i3 Platinum 8345 is our pick

The inTune i3 Platinum 8345 is our Chrysler, Dodge and Ram pick because it does the two jobs most owners in its year ranges actually need: it flashes preloaded tunes through the OBD-II port with no other tools required for the basic flash, and it leaves a path to CMR custom tunes from a dealer later. That combination matters because a stock or lightly modified truck rarely needs custom tuning on day one, but a truck that gains intake, exhaust or cam work later should not need a second device. The 8345 part number is the whole recommendation; the GM and Ford i3 parts are different numbers and this listing is not evidence for them.

DiabloSport inTune i3 Platinum 8345 key specs

• Manufacturer part number: 8345
• Verified ASIN: B08BJDM8H4, part number shown in the listing table
• Listed fitment: 2006-2014 Charger, 2005-2014 Durango, 2011-2014 RAM 1500, 2500 and 3500, 2003-2006 Chrysler PT Cruiser
• Install: plugs into the OBD-II port; no other tools required for the basic flash
• Tunes: preloaded performance programs for the specific vehicle, plus CMR custom-tune support on Platinum
• Adjustments vary by year and engine: DTC check and clear, speedometer calibration for gear ratio and tire size, cooling-fan control, fuel rich and lean adjustment, spark timing advance and retard, idle RPM, top-speed limiter, rev limiter, shift points, shift firmness, torque management, fuel-injector calibration
• Data logging: included on the Platinum family
• Emissions: a 50-state-legal version is stated to exist under CARB E.O. D-770 for the i3 family; this is not a guarantee that every 8345 listing is the 50-state version
• Maker-claimed gain for this listing: not published in the sources checked; GM-family i3 gains are not attributed to this Chrysler part
• Single-vehicle licensing: the i3 family offers additional vehicle licenses; a married device cannot simply move to a second vehicle without an unlock or license step

DiabloSport inTune i3 Platinum 8345: fits and best for

This part fits strictly the years and models in the listing title above. It is best for Chrysler, Dodge and Ram owners inside those ranges who want a handheld flash tuner with preloaded tunes and a later custom-tune path, and who do not need a permanent in-cab monitor. GM buyers need the 8245-family part, not this ASIN, and Ford buyers need a different part number again. Do not read the listing’s broad blurb as fitting Chrysler, Ford or GM generally; the part number and title narrow it, and the title wins.

DiabloSport inTune i3 Platinum 8345: what owners report

DiabloSport inTune i3 Platinum 8345: who should not buy

Do not buy the 8345 if your vehicle is outside the listed years and models, if you own a GM or Ford vehicle, or if you want a permanent gauge display in the cab. GM buyers should check the 8245-family part instead, and monitor buyers should look at the Trinity 2 EX 9200 below, after confirming its sub-model and fitment.

DiabloSport inTune i3 Platinum 8345: pair it with

Pair it with the maker’s fitment check before ordering, and with a CMR dealer contact if you plan modifications later, since custom tunes come from dealers rather than from the box alone. No accessory ASIN was verified in the research for this article, so no accessory button is attached to this pairing.

Touchscreen Monitor Pick: DiabloSport Trinity 2 EX 9200

Touchscreen Monitor Pick

Why the DiabloSport Trinity 2 EX 9200 is our pick

The Trinity 2 EX 9200 is our touchscreen pick because it is one device doing two daily jobs: it tunes the vehicle and it stays in the cab as a monitor with customizable gauge layouts. For a driver who checks temperatures, logs data or runs performance tests regularly, that permanent display is worth more than a second handheld that lives in the glove box. The caution is equally clear: the 9200 listing title is generic, its exact supported makes and years were not fully listed in the sources checked, and its emissions sub-model was not conclusively resolved, so fitment and sub-model must be confirmed before buying.

DiabloSport Trinity 2 EX 9200 key specs

• Manufacturer part number: 9200
• Verified ASIN: B077Q63XJW, first available November 8, 2017 in the listing record
• Display: full-color 5-inch capacitive touchscreen with customizable gauge layouts
• Tunes: preloaded tunes, plus CMR custom-tuning capability on EX Platinum
• Data logging: included; reads and clears DTCs
• Performance tests: 0-60 and quarter-mile tests in the feature lists
• Maker-claimed ceiling for the T2 EX family: up to an additional 100 HP and 250 TQ on diesel and 90 HP and 90 TQ on gas applications, asterisked in the source; a family ceiling, not a promise for any specific vehicle
• Emissions: EX Standard is stated as 50-state legal under CARB E.O. D-770 and is not CMR-compatible; Platinum models are stated as not 50-state legal in the same explainer; which sub-model 9200 is was not conclusively resolved
• PCM unlock: 2015 and newer Dodge, Ram and Chrysler vehicles require a PCM unlock in order to tune; a modified or unlocked PCM kit exists for those applications and the standalone 9200 is not sufficient evidence for a plug-and-tune claim on those years
• Exact supported makes and years for this ASIN: not fully listed in the sources checked

DiabloSport Trinity 2 EX 9200: fits and best for

This device is best for buyers who want one tuner and monitor with a large touchscreen, and who may later move to custom tunes on a Platinum sub-model. It is not a safe blind buy: confirm fitment for your exact vehicle from the maker’s application list, confirm whether your sub-model is Standard or Platinum, and budget for a PCM unlock kit if your Dodge, Ram or Chrysler vehicle is 2015 or newer. A buyer who only flashes once and never looks at gauges again is better served by a simpler handheld.

DiabloSport Trinity 2 EX 9200 pros and watch-outs

DiabloSport Trinity 2 EX 9200: what owners report

DiabloSport Trinity 2 EX 9200: who should not buy

Do not buy the 9200 if you cannot confirm its sub-model and your vehicle’s fitment, if you own a 2015 or newer Dodge, Ram or Chrysler vehicle and are unwilling to add a PCM unlock, or if you only want a cheap flash-and-remove handheld. Those buyers should look at the inTune i3 Platinum 8345 for the listed Chrysler, Dodge and Ram years, or wait until fitment is confirmed.

DiabloSport Trinity 2 EX 9200: pair it with

Pair it with a PCM unlock kit where the application requires one, and with a mount position that keeps the touchscreen readable without blocking vents or controls. No unlock-kit ASIN was verified in the research for this article, so no accessory button is attached to this pairing.

Ford Pick: SCT X4 Power Flash Programmer 7015 Ford

Ford Pick

Why the SCT X4 Power Flash Programmer 7015 Ford is our pick

The SCT X4 7015 is our Ford pick because it covers the full arc of a Ford owner’s tuning life: preloaded tunes for a stock or lightly modified truck, room for up to 10 custom tunes from an SCT dealer as modifications grow, Wi-Fi updates, and a backup of the factory tune for return to stock. That backup is not a footnote; it is what makes trying a tune reversible. The warning travels with the recommendation: a second listing circulates for the same part number, so the checker must eyeball the listing before publish, and this guide uses only the attribute-table ASIN below.

SCT X4 Power Flash Programmer 7015 Ford key specs

• Manufacturer part number: 7015, Ford variant only
• ASIN used here: B00J262R9A, from an attribute table for SCT 7015; a separate roundup links the same part number to B00JYMZMA8, which is not used here and must be eyeballed before publish
• Tunes: preloaded, maker-described tune files; stores up to 10 custom tunes
• Install: plugs into the OBD-II port, select the preloaded tune, device programs the vehicle
• Display: full-color backlit display with high-speed data logging and monitoring
• Diagnostics: reads and clears DTCs
• Updates: built-in Wi-Fi for updates
• Return to stock: backs up the factory tune
• Adjustments: shift firmness and shift points, global spark for timing across all RPM ranges, on-the-fly power adjustments where supported
• Emissions: SCT states its tuning will not modify or delete vehicle emissions and that its products comply with the Clean Air Act
• Application note: GM buyers need 7416 and Chrysler, Dodge, Jeep and Ram buyers need 7215, each with their own PCM-encryption limits; newer-model preloaded coverage is limited and must be checked against the current application list

SCT X4 Power Flash Programmer 7015 Ford: fits and best for

Part 7015 is the Ford X4, full stop. It is best for Ford owners who want preloaded tunes now plus room for up to 10 custom tunes from a dealer later, with Wi-Fi updates and a factory-tune backup. A dealer example in the sources covers 2011 to 2016 Ford 6.7L Power Stroke trucks with DPF-on, emissions-friendly tuning only, and that example must not be read as applying to gas X4 applications. Do not buy 7015 for a GM or Chrysler-family vehicle, and do not assume current-model-year preloaded coverage without checking the current application list.

SCT X4 Power Flash Programmer 7015 Ford: what owners report

SCT X4 Power Flash Programmer 7015 Ford: who should not buy

Do not buy the 7015 if your vehicle is not a Ford, if you need preloaded coverage for a current model year that the application list does not show, or if you want a tuner without any dealer involvement for custom tunes later. GM buyers should check part 7416 and Chrysler-family buyers part 7215, each with their own encryption limits noted above.

GM Truck Pick: Superchips Flashpaq F5 2845 GM

GM Truck Pick

Why the Superchips Flashpaq F5 2845 GM is our pick

The Flashpaq F5 2845 is our GM pick because it is the simplest honest handheld in this guide: economy, towing, daily driving and extreme levels where supported, speedometer correction after tire or gear changes, and DTC read and clear, on a color screen a first-time tuner can follow. It suits the large group of GM truck and SUV owners whose real need is a better daily tune and a corrected speedometer, not a custom-tune project. The caution is narrow but real: the ASIN was verified on an Amazon Canada listing, so the checker should eyeball the United States page for part 2845 before publish.

Superchips Flashpaq F5 2845 GM key specs

• Manufacturer part number: 2845, GM variant only
• ASIN used here: B017J844SY, verified on an Amazon Canada listing for Superchips 2845; the United States page should be eyeballed before publish
• Display: high-definition 2.8-inch color screen with a redesigned graphic interface
• Performance: increased memory with a faster processor, per the feature lists
• Tune levels: Economy, Towing, Daily Driving and Extreme Tuning where supported
• Speedometer correction: for tire-size and gear-ratio changes
• Limits: adjust speed and rev limiters; shift points, shift firmness and torque management, asterisked as varying by application
• Monitoring: vehicle-parameter monitoring; reads and clears DTCs
• Updates: internet-updatable via USB with updated software
• Emissions: EO number D-330-21 shown on F5 listings; verify which applications that EO covers rather than claiming blanket 50-state legality
• Maker-claimed gains, GM applications on premium fuel: add 20 rear-wheel HP on 5.3 trucks and 25 rear-wheel HP on 6.2 trucks; tunes for 87 octane and premium fuel provided; performance TCM tunes included; Ram-variant figures differ and are not used here
• Fitment summary: GM 1999-2016 applications in dealer summaries, including Silverado and Sierra, Tahoe, Yukon and Escalade, Camaro V8 and Corvette

Superchips Flashpaq F5 2845 GM: fits and best for

Part 2845 covers the GM applications in the dealer fitment summaries above. It is best for GM truck and SUV owners who want a simple handheld with clear tune levels and speedometer correction after larger tires or a gear change. It is not evidence for Ford or Ram fitment: the Ram variant is 3845 and the Ford variant is 1845 in dealer listings, each with its own gain figures. Some listed features are asterisked as unavailable on certain models, so check your application’s supported parameter list before buying for one specific adjustment.

Superchips Flashpaq F5 2845 GM: who should not buy

Do not buy the 2845 if your vehicle is not a GM application in the fitment summary, if you need a feature asterisked out for your model, or if you want Wi-Fi updates and custom tuning from a dealer network. Those buyers should look at the SCT X4 family for dealer custom tunes, after matching the right part number to their make.

50-State Gas Pick: Bully Dog GT Platinum Gas 40410

50-State Gas Pick

Why the Bully Dog GT Platinum Gas 40410 is our pick

The GT Platinum Gas 40410 is our gas pick because it is four products in one mount: engine tuner, monitor, gauge and diagnostic device, with 50-state-legal gas tuning with preloaded, emissions-compliant tunes on approved applications. For a gas-vehicle owner who wants tuning plus a permanent display, that single mount avoids a tuner in the glove box and a separate gauge pod on the pillar. The limits are stated just as plainly: it is gas only, its full supported year and model list was not completely enumerated in the sources checked, and its updater software needs a Windows PC.

Bully Dog GT Platinum Gas 40410 key specs

• Manufacturer part number: 40410, gas only; the diesel product is the separate 40420
• Verified ASIN: B001P20QDS, part number shown in the listing table
• Functions: engine tuner, monitor, gauge and diagnostic device in one unit
• Emissions: 50-state-legal gas tuning with preloaded, emissions-compliant tunes on approved applications, per the maker page
• Monitoring: real-time monitoring of more than 15 supported engine and powertrain parameters on customizable virtual gauges
• Driving Coach: coaching for fuel-saving driving habits
• Performance tests: 0-60, quarter-mile and braking tests
• Diagnostics: reads and clears DTCs
• Calibration: tire size, gear ratio and speedometer calibration; shift points and firmness where supported; functions and parameter support vary by application
• Custom tunes: stores up to 10 custom tunes in the GT Platinum family description
• Updates: Device Updater software is stated as not Mac-compatible; a Windows PC is required
• Maker-claimed gain for this gas part: no single headline gain figure was conclusively stated in the maker page checked, so none is printed here; diesel GT figures are not borrowed for this gas product
• Full supported year and model list: not completely enumerated in the sources checked; use the maker’s vehicle selector

Bully Dog GT Platinum Gas 40410: fits and best for

This part is best for gas-vehicle owners who want a 50-state-legal tuner plus a permanent in-cab monitor and gauge display with Driving Coach, in one mount. Diesel buyers need the separate 40420 GT Platinum Diesel, and any buyer whose vehicle is not on the maker’s selector for 40410 should not buy on the strength of this guide’s summary. Because functions and parameter support vary by application, the question to answer before ordering is not whether the GT can do a feature, but whether it can do that feature on your vehicle.

Older Unit Only: Edge Evolution CTS 85250

Older Unit Only

Why the Edge Evolution CTS 85250 is our pick

The Evolution CTS 85250 is included only as an older-unit pick, and that qualification is the recommendation. It suits a reader specifically looking for the older Evolution CTS unit, for example to match an existing mount or a known application, and it does not suit a reader buying a tuner fresh today. The listing text returned in research said the item was currently unavailable, with no word on if or when it would return, so this guide does not present 85250 as currently in stock, and new buyers should verify the current CTS3 variant for their truck first.

Edge Evolution CTS 85250 key specs

• Manufacturer part number: 85250, older CTS generation, not the current CTS3
• Verified ASIN: B003JIMN0U, with UPC 810115010593 in the listing record
• Availability at research check: listing text said currently unavailable, with no return date given
• Generation warning: CTS3 features and gains must not be attributed to this older unit
• CTS3 family context only, not verified for 85250: 5-inch full-color capacitive touchscreen, customizable gauges, OBD-II plug-in install, transmission temperature, boost and RPM monitoring, DTC read and clear, Wi-Fi updates and data logging
• CTS3 Cummins example, successor context only: gains of up to 175 HP and 470 lb-ft torque for 2003-2012 Ram 5.9 and 6.7 Cummins, not attributed to 85250
• Separate CTS3 records, not substitutes: a GM record and a Cummins record exist, but neither was selected as a pick because its variant-to-ASIN mapping needs its own eyeball
• Exact supported applications for 85250: not fully enumerated in the sources checked; CTS3 application ranges must not be copied onto 85250
• 85250-specific feature list: not verified beyond the part, brand and listing record above; unpublished specs are omitted, not guessed

Edge Evolution CTS 85250: fits and best for

This unit is best only for readers specifically seeking the older Evolution CTS unit for a known application or an existing mount. It is not a recommendation for a new purchase made on today’s availability, and it is not a stand-in for a CTS3. Anyone buying new should first verify the current CTS3 variant for their truck, confirm its part number against its own listing, and only then compare it with the other picks in this guide.

Spec comparison

Specs are given per exact part number. A cell marked Not published means the sources checked did not state that figure for that part, not that the device lacks the feature.

Fitment and installation basics

Flashing a tuner is a short job with a long checklist. First, confirm year, make, model, engine, transmission and PCM strategy, then match the part number in the maker’s fitment tool. Charge or support the battery before flashing, because an interrupted flash is the failure mode to avoid, and keep the vehicle undisturbed until the device reports the flash complete. Devices that back up the factory tune, such as the SCT X4, should have that backup confirmed before any custom tune is loaded. If your application needs a PCM unlock, as 2015 and newer Dodge, Ram and Chrysler vehicles do for DiabloSport tuning, fit the unlock kit first; the standalone tuner alone is not sufficient evidence for a plug-and-tune claim on those years. After flashing, check that DTCs read clear, that the speedometer reads correctly after any tire or gear change, and that the tune level matches the fuel in the tank. Electrical basics matter here too: read our amps draw guide, our winch battery wiring guide and our winch battery guide before working around vehicle electrics.

Safety essentials

Three items to have ready, named without buttons because no accessory ASIN was verified in the research for this article: Windows PC access for Bully Dog updates, a PCM unlock kit for 2015 and newer Dodge, Ram and Chrysler DiabloSport applications, and a readable mount position for touchscreen devices. None of these is a buy pick here, and none carries a button, because the research for this article verified no ASIN for them.

Troubleshooting

Who should NOT buy these

Owners outside every listed fitment range should not buy on hope. If your year, make, model or engine is not listed for a part number, that part is the wrong part, and waiting for a confirmed listing beats forcing a flash that the PCM rejects or a tune written for another engine.

Buyers chasing one headline gain number should not buy at all yet. Every gain in this guide is maker-claimed for one vehicle, one fuel and one tune level, and a family maximum is not your truck’s gain. If the only reason to buy is a number without an application attached, the purchase is not ready.

Emissions-delete shoppers should not buy from this guide. Delete and defeat products were deliberately excluded from this list, and no pick here modifies or deletes emissions equipment. A buyer who wants a delete tune needs a different conversation, not a workaround through these part numbers.

Mac-only owners should not buy the Bully Dog GT Platinum Gas 40410 without Windows access. Its updater is stated as not Mac-compatible, so updates stall without a Windows PC. Those buyers should prefer a device with Wi-Fi or cloud delivery where the maker states it.

New buyers should not hunt the older Edge Evolution CTS 85250. Its listing showed as currently unavailable, its 85250-specific features are unverified, and CTS3 features must not be assumed for it. Verify the current CTS3 variant first, or choose one of the other five picks after matching part numbers.

FAQ

What is an ECU tuner, and what does it change?

An ECU tuner is a device that reprograms the vehicle’s factory calibration through the OBD-II port, changing parameters such as fuel delivery, spark timing, shift points and speedometer calibration within the maker’s tune files. Flash programmers rewrite the calibration and can restore the stock tune, while inline modules adjust signals without flashing. Neither type is universal, and both are tied to exact part numbers and vehicle applications.

How do I know which part number fits my truck?

Start from year, make, model, engine, transmission and PCM strategy, then check the maker’s fitment tool and order by part number. For example, the SCT X4 is 7015 for Ford, 7416 for GM and 7215 for Chrysler, Dodge, Jeep and Ram, and the DiabloSport i3 and Superchips F5 split by make the same way. If your exact application is not listed, the part is wrong for your vehicle, regardless of brand.

Are the horsepower gains in this guide guaranteed?

No. Every gain here is maker-claimed, marked up to where the source marks it, and tied to one vehicle, one fuel or octane, and one tune level. A family ceiling, such as the Trinity 2 EX ceiling, is not a promise for any specific vehicle, and premium-fuel figures do not apply to 87-octane tunes. Treat gains as a comparison aid, and choose the tune level that matches your fuel and your use.

Can I use one tuner on two vehicles?

Not freely. Several devices here are married to one vehicle, and moving one to a second vehicle needs an unlock or an additional license step, where the maker offers one. The i3 family offers additional vehicle licenses, and the SCT X4 backs up one factory tune for return to stock. Check the licensing terms for your exact device before assuming a second vehicle is covered.

Do I need custom tunes, or are preloaded tunes enough?

Preloaded tunes suit stock or lightly modified vehicles on the octane you actually use. Custom tunes suit modified vehicles with intake, exhaust, head, cam or forced-induction changes, and they need a dealer to write them. Newer encrypted PCMs may require custom tuning even where older years had preloaded coverage, so check your model year’s position before deciding which path you need.

Will a tuner delete my emissions equipment?

No pick in this guide does that, and delete and defeat products were deliberately excluded from this list. Makers state that their street-legal versions do not modify or delete emissions equipment and that custom tuners must follow Clean Air Act guidelines. Check the exact variant’s legality for your state, because some versions of a family are 50-state legal while others are not.

Why does my 2015 or newer Dodge, Ram or Chrysler vehicle need a PCM unlock?

Those vehicles use a PCM strategy that DiabloSport tuning cannot reach with the standalone tuner alone, so a modified or unlocked PCM kit is required before tuning. Without the unlock, the tune cannot load, and no headline feature changes that requirement. Budget for the unlock kit as part of the purchase, and confirm the kit for your exact vehicle before ordering the tuner.

What is the difference between a flash tuner and an inline module?

A flash tuner rewrites the factory calibration through the OBD-II port and can restore the stock tune, which suits owners who want preloaded or custom tunes and diagnostics in one device. An inline module plugs into factory connectors, adjusts signals without flashing the PCM, and suits owners who want on-the-fly level changes or who do not want a flash. Both are application-specific, and no inline module is a buy pick here because no inline-module ASIN was verified.

Should I buy the older Edge Evolution CTS 85250?

Only if you specifically seek that older unit for a known application or an existing mount. Its listing showed as currently unavailable when checked, its 85250-specific features are unverified, and CTS3 features and gains must not be assumed for it. New buyers should verify the current CTS3 variant for their truck first, confirm its part number against its own listing, and compare it with the other picks here.
