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. Flashpaq #2848-DS now includes 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. Flashpaq also offers the ability to adjust throttle-pedal sensitivity in the device's menus with our built-in Throttle Booster feature while loading the selected tune. Every owner has their own preferences in pedal response, and with Flashpaq for 2017-2019 GM Diesel, you be able to set it exactly how you want it. Flashpaq allows an increase in throttle sensitivity from 0-50% above our calibration to optimize your driving experience. Add Power! 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.
