Features:

- The Premier DFM Solution for 3.0L 10-Speed Trucks!
The Pulsar LT is a new in-line module for 2019-2021 Chevrolet Silverado and GMC Sierra 1500 3.0L 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, and TPMS. 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.
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 or correct any codes that are set. GM has this feature laced into the calibration files and would require full ECM/TCM tuning to re-enable cruise control or to correct any other codes or drivability concerns
