The DiabloSport Pulsar is a groundbreaking inline tuning module engineered specifically for 2019–2022 Ram 5.7L HEMI trucks. Unlike traditional flash tuners, Pulsar requires no PCM swap, no computer removal, and no additional wiring harness. It plugs directly into the factory PCM and immediately delivers performance, drivability, and control—all while keeping your truck’s stock computer in place.
