The Pulsar LT is a new in-line module for 2020-2021 Chevrolet Silverado 1500 and GMC Sierra 1500 3.0L Duramax Diesel 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 can also be used to disable Auto Start/Stop, run a manual DPF regeneration cycle, transmission relearn and adjust your hi-idle function. It connects directly to the vehicle computer system, making installation a breeze and leaving your factory warranty intact. This product will NOT provide power(horsepower/torque) increases.

DmaxStore Note: 

• *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.*
