Featuring a true plug-and-play design, the Pulsar V3 installs in minutes with no cutting, splicing, or wiring required, and it’s just as easy to remove, leaving no trace for warranty work. Take complete control of your Duramax with on-the-fly power level adjustments directly from your factory steering wheel controls, no need for extra switches or bulky controllers. The Pulsar V3 also features a built-in throttle sensitivity booster for instant throttle response and a more aggressive driving experience, whether you’re towing heavy loads, daily driving, or pushing your truck on the open road. Designed with state-of-the-art standalone ECU-style technology, the Pulsar V3 gives you advanced control and safety. With integrated safety backdowns, your engine is always protected while still enjoying maximum performance. You can also calibrate for larger tires and make TPMS adjustments with ease. For drivers who demand more from their trucks, the Edge Pulsar V3 is the proven performance solution—combining unmatched power, reliability, and control for the modern Chevy Silverado and GMC Sierra diesel trucks. Pair it with an Edge Insight CTS3 monitor for even more features and control. *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. GM has this feature laced into the engine calibration files and would require full ECM tuning to enable cruise again.
