SOTF Tuning

When selecting SOTF tuning, you have the ability to utilize the Cruise Control Method (Read More Here) which would be accessed via your steering wheel. If you prefer a manual toggle switch, be sure to select the addon. If you do not select the addon, your SOTF tuning will automatically default to the Cruise Control Method.

• Unlocked ECM's will not be able to communicate with the GM Factory Tools, GM will not be able to flash or modify your ECM for recalls anymore.

The MPVI3 can unlock 2019-2023 Trucks*. Click here to learn more.

How it works

You will need to read the stock file of the truck with the HPTuners MPVI3 Device, once you send us that stock file, we can send you the custom tuning to suit your truck. It's a very quick and easy process and will come with step-by-step instructions.
