The DiabloSport inTune i3 Platinum + Unlocked PCM Kit is the complete tuning solution for 2018 Ram 2500 and 3500 trucks equipped with the 6.4L HEMI engine.

Whether you’re towing, hauling, or daily driving, these upgrades deliver noticeable improvements in both power and drivability. The Platinum i3 also supports CMR custom tuning, giving you the ability to work with DiabloSport’s nationwide tuner network to create dyno-proven calibrations tailored to your bolt-ons or advanced modifications. With built-in data logging, diagnostics, and user-adjustable options like speedometer calibration and MDS disable, you’ll have full control over your Ram’s performance. This kit includes the inTune i3 Platinum programmer and a DiabloSport Modified PCM shipped via cross-shipment, making installation seamless and keeping your stock PCM safe.
