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.

  Hey there I’m looking to delete a 2022 l5p I got the hp tuner mpvi 4 and e41 unlock and the parts needed but just looking for the tune file for a normal delete and maybe a 50hp tune if same price nothing fancy wondering what one I buy for that kinda thing thanks

  Hey there, if you have the MPVI4 you'll just need to purchase the tune files and the credits to flash the truck. You do not need the e41 tool on the 22 L5PS (only the 2017/2018 require it).
