Tuning

TCM Tuning

TCM Tuning is optional but highly recommended. Each TCM File will be built to suit and will include line pressure improvements to hold all the extra power that is made.

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.

ECM Unlock

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