The DiabloSport inTune i3 + Unlocked PCM Kit is the complete performance upgrade for the 2015-2017 Dodge Durango 5.7L HEMI. From the factory, these SUVs come with locked PCMs that block tuning, but this kit includes everything you need to safely unlock your Durango and unleash its true potential. The inTune i3 handheld programmer (PN 8345) comes preloaded with dyno-tested calibrations designed specifically for the 5.7L HEMI. When paired with the included DiabloSport Modified PCM, you can expect gains of up to 20 rear-wheel horsepower, stronger torque, sharper throttle response, and noticeably improved 8-speed transmission performance for smoother, more confident shifting. In addition to raw power, the i3 also lets you disable MDS (Multi-Displacement System) for consistent V8 power, recalibrate your speedometer for tire or gear changes, and adjust drivability features to suit your needs. For Durango HEMI owners who want more power, better drivability, and complete tuning control, the inTune i3 + Unlocked PCM Kit is the proven solution.
