Product Description
EDGE PRODUCTS 22412 PULSAR LT – 2019–2021 CHEVROLET SILVERADO / GMC SIERRA 1500 3.0L DURAMAX
The EDGE PRODUCTS 22412 PULSAR LT is the ultimate inline performance and control module for the 2019–2021 Chevrolet Silverado and GMC Sierra 1500 3.0L Duramax. This plug-and-play device installs directly onto the vehicle without ECM removal or flash tuning, giving owners access to throttle response adjustments, tire size recalibration, TPMS threshold modification, auto start/stop disable, and more—all without leaving a footprint in the factory ECM.
Pulsar LT is designed for drivers who want more control over their truck's behavior without committing to a flash tuner. Its inline architecture preserves factory emissions compliance while giving you instant access to the adjustments that matter most. Whether correcting speedometer readings after tire upgrades, improving pedal response, or modifying driver-assist features, Pulsar LT keeps you in command with seamless integration.
Installation takes minutes—no PCM unlocking, no tools beyond basic engine-bay access, and no disassembly of factory computers. Simply plug the Pulsar LT inline, calibrate via the steering-wheel controls, and enjoy a dramatically improved driving experience.
