The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the complete tuning solution for the 2020 Ram 1500 5.7L HEMI.

These improvements give your Ram more strength for daily driving and enhanced towing capability for heavy-duty work.\nFor 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.\n⚠️ 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.\nFor 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.
