DiabloSport PKITDR57ET21-I3 inTune i3 with Modified PCM

The DiabloSport inTune i3 + Unlocked PCM Kit is the complete performance solution for 2021 Ram 1500 trucks equipped with the 5.7L HEMI eTorque system. Factory PCMs on these models are locked, preventing traditional tuning, but this kit includes everything needed to safely unlock your Ram’s true potential. Preloaded with dyno-tested calibrations, the inTune i3 delivers gains of up to 30 rear-wheel horsepower over stock, along with noticeable improvements in torque output, throttle response, and 8-speed transmission behavior. The result is a Ram that pulls harder, shifts smoother, and responds instantly to your right foot—perfect for both towing and everyday driving. The Platinum i3 also supports CMR custom tuning, giving you the flexibility to have dyno-proven calibrations built for bolt-ons or advanced modifications. Built-in data logging ensures your setup can be optimized as your truck evolves. User-friendly features include MDS disable, speedometer calibration for larger tires, and adjustments to refine drivability to your preference. This performance kit includes the inTune i3 handheld programmer (PN 8345) and a DiabloSport Modified PCM, shipped via a one-time cross-shipment for a simple, hassle-free installation. For 2021 Ram 1500 eTorque owners who want horsepower, torque, towing strength, and sharper drivability, the inTune i3 + Unlocked PCM Kit is the upgrade your HEMI deserves. NOTE: ON 2021+ MODEL YEAR VEHICLES, YOU MUST SAVE YOUR STOCK CALIBRATION WITH YOUR TUNING DEVICE BEFORE REMOVING THE STOCK PCM FROM THE VEHICLE. PLEASE REFER TO THE INSTRUCTIONS THAT COME WITH YOUR UNLOCKED PCM.
