The Pulsar LT is a new in-line module for 2020-2022 Chevrolet Silverado and GMC Sierra 2500/3500 6.6L Duramax that offers complete adjustability of many features, all from your steering wheel controls. Without modifying your truck's ECM, Pulsar LT offers you the ability to adjust throttle response, tire size, gear ratio, TPMS, and your top speed limiter. Pulsar LT for Duramax can also be used to command a manual DPF regen cycle, automatic transmission relearn, clear DTC's and high idle the engine. It connects directly to the vehicle computer system, making installation a breeze and leaving your factory warranty intact. *When physically changing ring and pinion gears in the late model GM trucks, the factory cruise control will be disabled. While the Pulsar will allow you to recalibrate the speedometer for that gear change, it will not re-activate the disabled cruise control system. GM has this feature laced into the engine calibration files and would require full ECM tuning to enable cruise again.
