The DiabloSport Unlocked PCM is required to unleash the performance potential of your 2016 Ram 1500 5.7L HEMI. From the factory, these trucks are equipped with locked PCMs that prevent tuning, but this unlocked unit provides the foundation you need to take advantage of DiabloSport’s powerful tuning solutions. When paired with a DiabloSport inTune i3 or Trinity T2 programmer, you’ll gain access to dyno-tested performance calibrations that deliver more horsepower, stronger torque, sharper throttle response, and smoother shifting. Whether you’re towing, daily driving, or chasing maximum performance, the unlocked PCM opens the door to the upgrades your Ram deserves. ⚠️ Important Note: A DiabloSport tuner (sold separately) is required to install performance tunes. Modified PCMs are not compatible with other tuning brands. For Ram owners ready to move beyond factory restrictions, the DiabloSport Unlocked PCM is the key to unlocking real power and drivability improvements.
