Factory PCMs in these trucks are locked and prevent tuning. This modified PCM provides the unlocked foundation for performance calibrations with compatible DiabloSport tuning devices, including the inTune i3 or Trinity T2.

When paired with a DiabloSport tuner, the manufacturer states gains of 25+ RWHP over stock, along with sharper throttle response, more confident shifting, and increased towing strength.

User features include disabling Auto Start/Stop, adjusting speedometer calibration for larger tires, and customizing drivability.

For 2021 model-year vehicles, save the stock calibration with your tuning device before removing the factory PCM. Follow the included PCM instructions for installation.
