The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the complete tuning solution for the 2015 Dodge Charger 5.7L and 6.4L HEMI. From the factory, these models are equipped with locked PCMs that block tuning. This kit provides everything you need to safely unlock your HEMI’s full performance potential, including a DiabloSport Modified PCM and the powerful inTune i3 Platinum handheld programmer (PN 8345). With dyno-tested preloaded calibrations, the inTune i3 Platinum delivers 20–25 rear-wheel horsepower gains, stronger torque, sharper throttle response, and refined 8-speed transmission performance for faster, smoother acceleration. The result is a Charger that drives with more confidence, both on the street and at the track. For enthusiasts looking to add bolt-ons or pursue advanced performance upgrades, the Platinum i3 also supports CMR custom tuning, giving you access to DiabloSport’s nationwide network of tuners for dyno-proven, vehicle-specific calibrations. With built-in data logging and diagnostics, you can track, monitor, and refine your Charger’s performance as your build evolves. ⚠️ Important Note: On 2019+ models, you must save your stock calibration with your tuning device before removing the factory PCM. Instructions are included for a seamless installation. For 2015 Charger 5.7L & 6.4L owners who want real horsepower gains, sharper drivability, and future tuning flexibility, the inTune i3 Platinum + Unlocked PCM Kit is the ultimate upgrade.
