The DiabloSport inTune i3 + Unlocked PCM Kit is the complete performance tuning solution for the 2017 Ram 1500 5.7L HEMI. From the factory, these trucks are equipped with locked PCMs that prevent tuning—but this kit provides everything you need to safely unlock hidden power and drivability improvements. With dyno-tested performance tunes preloaded, the inTune i3 delivers gains of up to 30 rear-wheel horsepower, along with stronger torque, sharper throttle response, and refined transmission behavior. The result is a Ram 1500 that pulls harder, shifts smarter, and performs better in every driving scenario—from daily commuting to heavy towing. The handheld also includes powerful user-adjustable features such as speedometer calibration for larger tires, the ability to disable MDS, and other fine-tuning options to tailor your truck’s performance. This kit includes the inTune i3 handheld programmer (PN 8345) and a DiabloSport Modified PCM shipped via cross-shipment, ensuring a seamless installation process. Once installed, you’ll be ready to load tunes, unleash horsepower, and experience the full potential of your HEMI-powered Ram. For owners who demand more power, better towing performance, and a more responsive driving experience, the DiabloSport inTune i3 + Unlocked PCM Kit is the ultimate upgrade for the 2017 Ram 1500 5.7L.
