Pulsar LT for 2019-2022 GM Gas Trucks

Customize your Silverado or Sierra, all without modifying the factory ECM or voiding your warranty.

The Pulsar LT is a new in-line module for 2019-2022 Chevrolet Silverado 1500 and GMC Sierra 1500 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 and Dynamic Fuel Management. It connects directly to the vehicle computer system, making installation a breeze and leaving your factory warranty intact. And yes, it does work on 6.2 10-speed models.

*Note - 2022 refreshed models are not supported. The 12th digit of the VIN will verify this; if it is 5 or higher, the Pulsar LT will not work. 4 and lower are supported for the 2022 model year.

*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
