Higher power files can be written for trucks with the right modifications.

1. Turn cruise control off and let go of all cruise buttons.
2. Hold CANCEL for about one second, then release it to open the menu.
3. Tap RES/ACCEL to go up one level or DECEL/COAST to go down one, releasing the button between taps.
4. Hold CANCEL for about one second to close the menu, or leave the buttons alone for about five seconds. Your level stays set until you change it or cycle the key.

With cruise control off and the power menu closed, stop the truck, then hold SET while you press the accelerator. Fueling tapers as the engine nears 2,000 RPM. Let go of SET to return to normal pedal control. Staging also turns off once the truck reaches 5 mph (8 km/h).
