Superchips 2848-DS - 2017-2019 GM L5P FLASHPAQ W/ UNLOCK

The 2017 to 2019 L5P GM Duramax Flashpaq performance programmer now features 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 provided 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 350 Feet-Pound 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. Flashpaq now features hardware and software allowing installers to unlock the ECM on their own, which means it is not necessary to remove the ECM from the vehicle and send it in. This also means you'll be tuning your truck in minutes, with NO VEHICLE DOWNTIME shipping parts back and forth. It has never been easier to add real power to an L5P Duramax. A notable feature is the 'Keep Drive Modes' function which will remember your last settings for Exhaust Braking, Tow/Haul mode, and Grade Braking. This means you no longer have to manually turn them on every time you restart your truck.
