Fits 2017-2019 Chevrolet Silverado/GMC Sierra 2500/3500 - ECM Unlock

Flashpaq offers up to an additional 150-horsepower and 350ft-lbs torque! Once the ECM is unlocked with the included software and harness (a one-time operation to the vehicle), our pre-loaded tunes can be flashed into the truck to fine tune it for daily driving, towing, fuel mileage or all-out performance. Our tuning has gone through extensive testing and is proven to perform without undue stress on an otherwise stock truck.
