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! *Physical gear ratio changes made in the 2019-2022 trucks will affect your cruise control functionality. This is an issue within GM's platform. While this device will calibrate your speedometer for an accurate display after making a gear ratio change, it will not re-enable the non-functioning cruise control.
