The DiabloSport inTune i3 + Unlocked PCM Kit is the complete tuning solution for the 2015 Ram 1500 5.7L HEMI with the 6-speed automatic transmission. Factory PCMs block tuning, but this package provides everything you need to safely unlock your truck’s true performance. The kit includes the inTune i3 handheld programmer (PN 8345) and a DiabloSport Modified PCM delivered via cross-shipment. Preloaded with dyno-tested calibrations, the i3 delivers gains of up to 25–30 rear-wheel horsepower, improved torque, sharper throttle response, and refined 6-speed transmission behavior for smoother, quicker shifting. For drivers planning upgrades, the Platinum i3 also supports CMR custom tuning, giving you access to DiabloSport’s nationwide tuner network for dyno-proven calibrations tailored to bolt-ons or advanced modifications. Built-in data logging and diagnostics make it easy to monitor and fine-tune your Ram’s performance as your build evolves. For 2015 Ram 1500 owners looking for horsepower, torque, better drivability, and custom tuning flexibility, the inTune i3 + Unlocked PCM Kit is the ultimate upgrade.
