The DiabloSport inTune i3 + Unlocked PCM Kit is the all-in-one tuning solution for the 2015 Ram 1500 5.7L HEMI. From the factory, these trucks are built with locked PCMs that block tuning, but this package includes everything you need to safely unlock your HEMI’s performance potential. The kit includes the inTune i3 handheld programmer (PN 8345) and a DiabloSport Modified PCM, giving you immediate access to preloaded dyno-tested performance tunes. With these calibrations, you can expect 25–30 rear-wheel horsepower gains, stronger torque, sharper throttle response, and refined transmission behavior for smoother, more confident shifting. For Ram owners who want more flexibility, the Platinum i3 also supports CMR custom tuning, allowing dyno-calibrated tunes built specifically for your bolt-ons or advanced upgrades. With built-in data logging and diagnostic features, you’ll be able to track and fine-tune your truck’s performance as it evolves. With easy installation via DiabloSport’s cross-shipment PCM process, this kit gives you everything you need to transform your Ram into a more powerful, responsive, and enjoyable truck to drive. For 2015 Ram 1500 5.7L HEMI owners, the inTune i3 + Unlocked PCM Kit is the proven path to horsepower, torque, and drivability improvements.
