Compatible with 2020 RAM 1500 - 5.7L

Part Number: PKITDR578S20-I3

The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the complete tuning solution for the 2020 Ram 1500 5.7L HEMI. From the factory, these trucks are equipped with locked PCMs that prevent performance tuning, but this kit provides everything you need—an unlocked DiabloSport Modified PCM and the inTune i3 Platinum handheld programmer (PN 8345)—to unleash your Ram’s hidden power. Preloaded with dyno-tested calibrations, the inTune i3 Platinum delivers up to 30 rear-wheel horsepower gains, improved torque, sharper throttle response, and refined 8-speed transmission performance for smoother, more confident shifting. These improvements give your Ram more strength for daily driving and enhanced towing capability for heavy-duty work. For enthusiasts planning bolt-ons or advanced builds, the Platinum i3 supports CMR custom tuning, enabling dyno-proven calibrations tailored to your setup. With built-in data logging and diagnostics, you can monitor and refine your truck’s performance with precision. ⚠️ Important Note: On 2019+ model year vehicles, you must save your stock calibration with your tuning device before removing the factory PCM. Detailed instructions are included for a seamless process. For 2020 Ram 1500 5.7L HEMI owners who want real horsepower gains, better drivability, and stronger towing performance, the inTune i3 Platinum + Unlocked PCM Kit is the ultimate upgrade.
