The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the all-in-one tuning solution for the 2018 Dodge Charger Hellcat. From the factory, these supercharged HEMI models are locked down against tuning, but this package includes everything you need—an unlocked DiabloSport Modified PCM and the inTune i3 Platinum handheld programmer (PN 8345)—to safely unleash your Hellcat’s full potential. With dyno-proven calibrations preloaded, the inTune i3 Platinum delivers up to 30 rear-wheel horsepower gains, stronger torque, sharper throttle response, and refined 8-speed transmission performance for smoother, faster shifts. The result is a Hellcat that accelerates harder, reacts quicker, and drives with the aggressive edge you expect from a Dodge SRT. For drivers planning bolt-ons or advanced builds, the Platinum i3 also supports CMR custom tuning, giving you access to DiabloSport’s nationwide network of tuners for dyno-calibrated performance tailored to your upgrades. Built-in data logging and diagnostics make it easy to monitor, track, and fine-tune your car’s performance as your build evolves. ⚠️ Important Note: On 2019+ vehicles, you must save your stock calibration with your tuning device before removing the factory PCM. Instructions are included for a smooth and seamless installation. For 2018 Charger Hellcat owners who want serious horsepower gains, sharper drivability, and maximum tuning flexibility, the inTune i3 Platinum + Unlocked PCM Kit is the ultimate performance upgrade.
