2017 F150 / Raptor - How to Return to Stock Using the nGauge
One of the files included when you receive your MPT tunes is titled: “StockFile-Engine-Trans.enc” You'll use this file to return the vehicle to stock. The standard procedure on the nGauge for returning to stock doesn’t apply to the 2017+ vehicles. In order to “return to stock” you will use the same function as installing a custom tune: “Load Tune” and select this file. This is an exact copy of your stock file and will need to be loaded and driven before going to the dealer for any type of service.
Prior to Step 1- Ensure your nGauge tuner has the microSD inserted, and that the OBDII cable is plugged in to the OBDII port of the vehicle.

Step 4 – The nGauge will confirm “Flash this tune”? Tap check. Confirm time to flash in next screen by tapping check.
Step 5 – When prompted to Turn Key On, make sure to turn the key on without turning on ignition.
