DiabloSport Computer Tuner/Programmer for 21-22 Ram 1500 5.7

The DiabloSport Unlocked PCM is required to tune your 2021 Ram 1500 5.7L HEMI eTorque, giving you access to real performance improvements with compatible DiabloSport devices like the inTune i3 or Trinity T2. From the factory, these trucks come with locked PCMs that prevent tuning, but this unlocked PCM provides the foundation you need to install performance calibrations safely and effectively.\nWhen paired with a DiabloSport tuner, you’ll unlock gains of 25+ RWHP over stock, along with sharper throttle response, more confident shifting performance, and increased towing strength. You’ll also be able to take advantage of user features such as disabling Auto Start/Stop, adjusting speedometer calibration for larger tires, and customizing drivability to fit your needs.\n⚠️ Important Note: For 2021+ model year vehicles, you must save your stock calibration with your tuning device before removing the factory PCM. Be sure to follow the instructions included with your unlocked PCM for a smooth installation.\nFor Ram 1500 eTorque owners ready to take the next step in performance tuning, the DiabloSport Unlocked PCM is the first and most important upgrade.
