If you've shopped for performance upgrades for you '15-18 RAM 6.4L truck, odds are you've come to the realization that "tuning" these trucks is easier said than done. Superchips offers a PCM swap for the 15-UP HEMI 2500 6.4L trucks, but we're well aware that consumers are interested in other options to add performance. Pulsar is a brand new, innovative product that has been engineered to keep your PCM on the truck with no flash tuning, or removal of the computer itself, required. Pulsar is an in-line computer that connects directly to the vehicle PCM, with no additional wiring harness (do we have your attention yet?!).
