Pulsar LT In-Line Control Module 2014-2018 Silverado & GMC Sierra 1500 5.3L

The Pulsar LT is a new in-line module for 2014-2018 5.3L Chevrolet Silverado 1500 and GMC Sierra 1500 and 2015-2020 5.3L/6.2L GM Tahoe/Suburban/Escalade/Yukon and 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. It can also be used to disable your Active Fuel Management system! It connects directly to the vehicle computer system, making installation a breeze and leaving your factory warranty intact.

Note: Works in 2019 Classic Silverado/Sierra trucks

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
