| Description_EXT | Compatible with 2021 RAM 1500 - 5.7L 8-Speed except E-Torque |
| Description_MKT | The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the complete tuning solution for the 2021 Ram 1500 5.7L HEMI. From the factory, these trucks ship with locked PCMs that prevent tuning. This package includes a DiabloSport Modified PCM and the inTune i3 Platinum handheld programmer (PN 8345), giving you everything you need to safely unleash your Ram’s full potential. |
| Description_MKT | Preloaded with dyno-tested performance calibrations, the inTune i3 Platinum delivers up to 30 rear-wheel horsepower gains, stronger torque, quicker throttle response, and refined 8-speed transmission behavior for faster, smoother shifts. These improvements provide more confident acceleration, towing strength, and daily drivability. |
| Description_MKT | The kit also allows for MDS (Multi-Displacement System) disable, keeping your HEMI in full V8 mode whenever you want maximum performance. For enthusiasts adding bolt-ons or advanced upgrades, the Platinum i3 supports CMR custom tuning, giving you access to DiabloSport’s nationwide network of tuners for dyno-proven calibrations tailored to your build. Built-in data logging and diagnostics make it simple to monitor and fine-tune your Ram’s performance. |
| Description_MKT | ⚠️ Important Note: On 2021+ models, you must save your stock calibration with your tuner before removing the factory PCM. Instructions are included for a smooth installation. |
| Description_MKT | For 2021 Ram 1500 5.7L HEMI owners who want real horsepower gains, MDS disable, and sharper drivability, the inTune i3 Platinum + Unlocked PCM Kit is the ultimate performance upgrade. |
