2015+ HEMI / Pentastar PCM Unlock and Custom Tuning

Dodge, Jeep, RAM, and Chrysler mail-in service

Permanently unlock your PCM and select the tuning level that fits your vehicle.

Why Go Beyond Just Unlocking?

Most 2015+ FCA/Stellantis vehicles use a locked PCM that prevents normal tuning access. We permanently unlock the PCM for HP Tuners or DiabloSport and can also install custom calibration changes for improved power, throttle response, shifting, and drivability.
