The 2020-2023 L5P GM Duramax Flashpaq performance programmer (PN 2848-DS1) now includes hardware and software to UNLOCK YOUR ECM AND TCM AT HOME, and contains tunes engineered with the daily driver, heavy tower, and enthusiast in mind. Once the ECM/TCM are unlocked with the included software and harnesses (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.
