Note: You will require an Unlocked TCM and 4 Credits in order to flash the tune file

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.

You will need an HP E41 ECM Upgrade Kit in order to unlock the ECM on 2017 and 2018 models. *These products are not included in the price, and you must select an addon* The MPVI3 can unlock 2019-2023 Trucks*. Click here to learn more.

You will need to read the stock file of the truck with the HPTuners MPVI 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.
