Transmission Tuning

TCM Tuning is optional but highly recommended if you have the T87 TCM. 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.

All Tuning will give you full access to calibrate, log, and scan via the OBD2 port with your MPVI4 and VCM Suite 4.3+!

Optional TCM Tuning:

If you choose to Add TCM Tuning, it will include:

• HPTuners TCM
• TCM Tune Files

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 MPVI4 can unlock 2019-2023 Trucks*. Click here to learn more.

Note: These 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.

You will need to read the stock file of the truck with the HPTuners MPVI4 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.
