Superchips | 2019-20 Silverado Performance Tuning is Here


After years of research and engineering development, Superchips is proud to announce Flashpaq tuning coverage for 2019-2020 5.3L and 6.2L V8 applications with the 6-, 8-, and 10-speed transmissions.

The all-new GM Flashpaq performance programmer (PN 2847-S) comes pre-loaded with tunes developed specifically for daily driving, towing, and performance enthusiasts. The Mileage XS, Tow, 87 Octane, 91 Octane and 93 Octane tunes offer significant 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 Superchips’ ECM Send-In process, so your truck’s ECM needs to be removed and shipped to them for unlocking. Once their 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 to limit downtime to as little as three days. Superchips says the 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.
