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. 

Transmission Tuning

TCM Tuning is optional but highly recommended if you have the T93 TCM. Each TCM File will be built to suit and will include line pressure improvements to hold all the extra power that is made.

You will require one of the following products in order to unlock the ECM. *These products are not included in the price and you must select an addon*. Click here to view a breakdown of L5P ECM Unlock Methods.

• HP E41 ECM Upgrade Kit
• L5P E41 ECM
• In-House ECM Unlock

How it works

You will need to read the stock file of the truck with the HPTuners MPVI2 or 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.
