2017-2019 GM Diesel tuning for Silverado HD and Sierra HD is finally here with the all-new Flashpaq 2847-DS. Available L5P Duramax engines. Our calibrations team spent a lot of time perfecting our tunes to give you everything you’ve come to expect from a Superchips tuner. By adjusting torque outputs at lower pedal inputs, you’ll love the new throttle response. Adjustments to rail pressure, injection pressure, and injection timing offer better power and torque throughout the RPM range, while helping to improve fuel economy as well.
On top of our performance tuning, Flashpaq also offers custom features like speedometer calibration for tire size and gear ratio changes, speed limiter adjustment, TPMS adjustment, Manual DPF Regens, Adaptive Transmission Learn, Engine Idle Up and the ability to read and clear codes. All-new to this device is our ‘Keep Drive Modes’ feature which will remember your last driver settings for Exhaust Braking, Tow/Haul Mode, and Grade Braking so you no longer have to manually turn those features on every time you restart your truck.
Flashpaq also offers end users the ability to adjust throttle pedal sensitivity within the device. Every owner has a preferred pedal feel and with Flashpaq for 2017-2019 GM Diesel, you have the control to set it exactly how you want it. Set throttle sensitivity anywhere from 0-50% above our calibration to optimize you driving experience.
This device includes our ‘ECM Send-In’ process, which will require you to remove your trucks factory ECM and ship it to us for unlocking. Once our specialists create the internal ECM modifications, it will be returned to you for re-installation into the truck, where you can then tune with your choice of calibration within the Flashpaq device. The purchase of the Flashpaq 2847-DS includes the cost of the ECM Unlock and Next Day Air return shipping of your ECM. Consumers should expect a 24-48hr turnaround time, so we do our absolute best to limit your trucks down time to as little as three days. Our ECM modifications are safe, reliable and compatible with GM dealer tools and flashes. So, your local dealer can still interact with your truck after you’ve returned your Flashpaq tuning to factory settings.
