2019+ Silverado tuning is finally here with the all-new Flashpaq 2847-S. Available for 2019-2020 Silverado and Sierra with 5.3L and 6.2L engines Flashpaq offers up to an additional 45-horsepower (max gains in 6.2L)! The all-new GM Flashpaq performance programmer (PN 2847-S) comes pre-loaded with tunes developed specifically for daily driving, towing, and performance enthusiasts. Our Mileage XS, Tow, 87 Octane, 91 Octane and 93 Octane tunes offer incredible torque gains throughout the RPM range with the improved drivability you’ve come to expect from Superchips.
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 spark advance offer better power and torque throughout the RPM range, while helping to improve fuel economy. Changes in engine speed limitations allow you you feel that massive power and torque curve for longer. You’ll also notice an improved pedal feel when running in the trucks factory ‘Sport’ mode for an the exciting driving experience you didn’t think possible in a 1/2-ton truck.
This device includes our ‘ECM Send-In’ process, which will require your trucks factory ECM to be removed and shipped 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-S includes the cost of the ECM Unlock and Next Day Air return shipping of your ECM. So we can limit down time to as little as just 3-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.
