The DiabloSport Pulsar is the innovative tuning solution built specifically for 2015–2018 Ram 2500 and 3500 trucks with the 6.4L HEMI engine. Traditionally, tuning these heavy-duty HEMI trucks has been a challenge due to locked PCMs, but Pulsar changes everything by delivering power and drivability gains with no PCM swap, flash tuning, or computer removal required.
