The much-anticipated Flashpaq tuning with ECM Mod for 2019-2022 Silverado and Sierra is finally here! Available for 5.3L and 6.2L applications Flashpaq tuning offers up to an additional 45-horsepower!* 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. This device REQUIRES YOUR ECM TO BE SHIPPED TO US TO BE UNLOCKED PRIOR TO INSTALLING TUNING. Purchase includes our ECM Send-In process, so your truck's ECM needs to be removed and shipped to us for unlocking. Once our specialists create the internal ECM modifications, they 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 to limit downtime 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. *Gains collected from 6.2L application
