Tuning and Diagnostic Support for GM Vehicles

Tuning and Diagnostic Support for GM Vehicles

HP Tuners offers the most comprehensive diagnostic and tuning software for GM vehicles in the industry, from the 1997 Corvette LS1 to the 2021 Camaro, 2020 Colorado, and the 2017+ GMC Sierra/Chevy Silverado 2500/3500/4500/5500 6.6L Duramax (diesel). We’ve been developing and refining ECM tuning and diagnostic support for General Motors for over 10 years and are committed to being first to market with support for new vehicles from Chevrolet, Buick, GMC, and Cadillac.

For enthusiasts, our MPVI3 OBDII interfaces and VCM Suite tuning software give you one of the most powerful and inclusive scanning, diagnostic, logging, and tuning products on the market. For professional GM tuners, you can offer custom tuning and calibration solutions for your customers with the newest GM vehicles, like the 2019 Corvette ZR1 and the L5P 6.6L Duramax equipped Chevy and GMC diesel HD trucks, via RTD and Tune Delivery Network (TDN).

For the latest vehicles with locked ECMs, PCMs, or TCMs, we offer services that upgrade your control modules and let you connect, read, edit, and write your vehicle through its OBDII port (see below for details). We even have support for other GM control modules such as the T87A 8 and 10-speed transmissions and Fuel Pump Control Modules.

GM Tuning Features Include:

  • First to market with custom tuning support for the 2023 Chevy Silverado/GMC Sierra L5P (requires E41 unlock).
  • TCM (unlock) support for T87A 8 and 10-speed transmissions.
  • Several ECM/PCM/TCM upgrade services available for different GM engines and transmissions, including the L5P ECM.
  • Support for programming the CCM Active Exhaust controller.
  • FPCM Fuel Pump Control Module support.
  • Support for GMPP Connect and Cruise tuning and GM Crate Motor controller tuning.
  • Comprehensive GM Diesel Support, including L5P Duramax with L5P ECM upgrade services available, and Diesel Switch and Switch on The Fly Software.

Note: 2017+ GM 8-Speed and 10-Speed T87A TCMs require an upgrade via HP Tuners’ GM TCM Unlock service before tuning. Our PCM Upgrade Service is required for 19 ZR1, Silverado L5P trucks, and Silverado E90 trucks.
