Edge Pulsar LT for 2019-2022 GM Gas Trucks 22451
Take command of your GM truck's performance with the Pulsar LT, the ultimate inline control module designed for late-model GM applications. Engineered for seamless integration, the Pulsar LT installs directly into your vehicle's computer system, no tuning, no permanent modifications, and no hassle. With this innovative device, you can adjust throttle response, tire size, gear ratio, TPMS settings, and even enable or disable features like Active Fuel Management (AFM) or Dynamic Fuel Management (DFM) in seconds.
Perfect for Silverado, Sierra, Tahoe, Suburban, Colorado, and Yukon owners, the Pulsar LT delivers a new level of customization without voiding your factory warranty. Easily recalibrate your truck for larger tires or gear changes, optimize fuel efficiency, or unleash sharper throttle response for a more engaging driving experience. The on-the-fly adjustability and plug-and-play design make it one of the most versatile upgrades available for GM trucks.
Whether you're towing, off-roading, or simply cruising, the Pulsar LT ensures your truck performs exactly the way you want it to. Experience smoother shifts, improved drivability, and full control of your vehicle's key functions all without a complex installation.
*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
