Description
Unleash the full potential of your 6.6L gas-powered Silverado or Sierra HD with the Edge Pulsar LT, a powerful plug-and-play performance module designed for 2020–2023 Chevrolet Silverado and GMC Sierra 2500/3500 HD trucks. This innovative in-line module offers complete adjustability directly from your steering wheel controls — no ECM modification needed.
With the Pulsar LT, you can fine-tune throttle response, recalibrate for larger tires or gear changes, adjust the top speed limiter, set TPMS pressure thresholds, and clear engine trouble codes — all while keeping your factory warranty fully intact. Designed for simplicity and power, this module is perfect for truck owners looking for flexibility without permanent changes.
Important Note: Changing ring and pinion gears in these trucks disables cruise control. Although Pulsar LT can recalibrate your speedometer, it does not restore cruise control functionality. Full ECM/TCM tuning is required to correct these issues.
