DiabloSport 32453 PULSAR for 2019-2022 Ram 1500 5.7L Hemi

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.\nThe redesigned Pulsar features a durable new enclosure and an updated internal board for improved reliability and expanded functionality. With the latest version, you can even read and clear diagnostic trouble codes directly through the module, adding convenience to its long list of capabilities.\nOnce installed, Pulsar transforms the way your Ram drives. You can adjust for larger tires or gear ratio changes with built-in speedometer calibration, disable the Multi-Displacement System to enjoy full-time V8 power, and sharpen throttle response for a more engaging driving experience. Pulsar also delivers gains of up to 30 horsepower and 30 lb-ft of torque, with power levels adjustable on the fly using your factory cruise control buttons.\nFor 2022 Ram models, compatibility depends on PCM type. Trucks equipped with the GPEC2A PCM (with two harness connectors located on the top/front of the ECM) are supported. Vehicles with the newer GPEC5 PCM are not compatible at this time, so be sure to confirm your truck’s PCM before purchase.\nThe DiabloSport Pulsar for Ram HEMI is the only inline performance module of its kind, delivering instant power, control, and convenience without ever cracking open your PCM.
