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 MPVI3 and VCM Suite 4.3+! 

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 Tuners E41 Unlock Kit (Cost Effective)
• L5P E41 ECM
• In-House ECM Unlock

• You will need an Unlocked ECM to flash the tuning onto your truck, if you do not have one, please select one of the addons. 
• 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 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.
