Factory PCMs in these trucks are locked and block aftermarket tuning. This modified PCM is professionally unlocked to enable tuning with compatible DiabloSport devices, including the inTune i3 and Trinity T2 Platinum.
When paired with a DiabloSport tuner, the PCM supports performance calibrations. The manufacturer states gains of 25–30 RWHP, along with stronger torque, sharper throttle response, and refined transmission behavior for smoother, quicker shifting.
Installation uses DiabloSport’s cross-shipment process. This PCM is not compatible with other tuning brands.
