Superchips Flashpaq Fits 2017-2019 Chevrolet Silverado/GMC Sierra 2500/3500 - ECM Unlock - 2848-DS

The 2017-2019 L5P GM Duramax Flashpaq performance programmer (PN 2848-DS) now includes hardware and software to UNLOCK YOUR ECM AT HOME, and contains tunes engineered with the daily driver, heavy tower, and enthusiast in mind. 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. At its maximum power level, Flashpaq for L5P can add up to 150 horsepower and 350ft-lbs of torque without ever turning a wrench. We also know reliability is critical, and our tuning has gone through extensive testing for performance gains without putting undue stress on an otherwise stock truck.
