2019-2022 RAM 5.7 HEMI performance has arrived! 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?!. The all-new, re-engineered Pulsar for Ram Hemi is here and better than ever! As the only inline module on the market today for performance tuning and feature control without requiring modification to the factory PCM, Pulsar is an excellent option for your Ram Hemi owners. The all-new enclosure design replaces our original case for improved durability, reliability and more modern stylish looks. Along with the new case design, we've re-engineered the internal board for increased durability, and performance with the ability to now clear diagnostics trouble codes. Pulsar For Ram Hemi offers multiple features like speedometer calibration for larger tires or gear ratio changes, disabling your Multi-Displacement System (keep it a V8 all the time!), improved pedal sensitivity, and add as much as 30hp/30ft-lbs of torque with power adjustment on the fly through your cruise control buttons! *2022 Ram Owners - Because of supply chain issues at Chrysler, some 2022 model trucks were built and shipped with a different GPEC5 PCM, which will not work with the Pulsar 32453. If you own a 2022 model, please verify your ECM has the two harness connectors located on the side of the ECM, not along the top narrow edge. Your vehicle will need the GPEC2A ECM in order for Pulsar to work.
