GM tuning + controller services
Start with
the vehicle.
Or the PCM.
Choose the vehicle family, the job you are doing, or the controller on the bench. We’ll narrow the hardware, licensing and tuning service from there.
01 / TRUCKS + SUVs
1500s.
HDs.
Full-size SUVs.
Remote and mail-in tuning for supported Chevrolet, GMC, and Cadillac trucks and SUVs. Choose the model family first; generation, engine, and controller come next.
1500 trucks
HD + Duramax
Full-size SUVs
1996–2006
Vortec and Gen III applications, including Black Box and P01/P59 controller families.
2007–2013
Gen IV truck and SUV applications, commonly using E38 or related controller families.
2014–2018 trucks
2015–2020 SUVs
Gen V Silverado and Sierra trucks, plus Tahoe, Suburban, Yukon and Escalade SUVs. Exact model year matters because GM staggered the platform changes.
2019+ trucks
2021+ SUVs
Current-generation Silverado, Sierra, Tahoe, Suburban, Yukon and Escalade applications. Some controllers require an unlock or additional access before tuning.
02 / PERFORMANCE CARS
Camaro. Corvette. CTS-V.
Mail-in and remote calibration paths for supported LT1-powered, LS-based, LT-based, and supercharged V-series applications—from mostly stock street cars to modified combinations that need a custom file and data-log review.
I need hardware + tuning
Choose the vehicle first. We’ll confirm the compatible HP Tuners interface, controller access and expected credit requirement.
I already own a device
Own a compatible MPVI or RTD-family device? Purchase the custom calibration separately.
03 / OTHER SUPPORTED GM
More than the first category tree.
Colorado, Canyon, Avalanche, TrailBlazer SS, Hummer, Pontiac G8, Cobalt SS, ATS, CTS, CT4, CT5, and other GM applications may be supported even when a dedicated vehicle page is not published yet.
Send the exact year, model, engine, modifications, and controller information. We’ll confirm the correct mail-in, remote-tuning, unlock, or controller-service path before you buy.
04 / ENGINE SWAPS + VATS
Make it run where
it belongs now.
Building an LS swap, getting a Vortec truck back on the road, or replacing a failed controller? Start with the PCM family. We handle VATS removal for factory vehicles and swaps without pretending they are the same job.
06 / REMOTE TUNING
Choose what you need.
I need a device
RTD4 is the straightforward tuner-managed path. MPVI4 is for customers who want full scanning, diagnostics, logging and VCM Suite capability.
I have the hardware
Purchase the custom engine tune, add transmission tuning when applicable, and buy required HP Tuners credits directly from HP Tuners.
