The much-anticipated Flashpaq tuner for 2019-2022 Silverado and Sierra is finally here, with revolutionary in-cab ECM/TCM Unlock! Available for 5.3L and 6.2L applications, Flashpaq tuning offers more horsepower and can unlock/flash right from your driveway. The all-new GM Flashpaq performance programmer (PN 2849-F) 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 all-new process completely changes everything you once knew about tuning your GM 1500 truck and will lead our industry into the future with even more capabilities, saving you time and money when it comes time to modify your truck. Enable our 'Remember Last Setting' feature that allows your truck to remember your Start Stop and Drive Mode settings every time you start your truck. We can also disable your AFM/DFM systems to maintain V8 mode all the time. Calibrate your speedometer for larger tires or gear ratio changes. Adjust your TPMS settings, even fine tune your throttle sensitivity with the built in throttle booster feature.

**Device can unlock and tune only one vehicle. Once the ECM is unlocked and flashed, the flash can be returned to factory settings, but the Unlock process can not be reversed. If VIN lock and ECM Unlock has been completed, device is non-returnable

100 cotton
Size: 33W x 32L, Color: Midnight Selvedge
These are great, just keep in mind that 100% cotton is not the same as 99 cotton 1 elastane, so size up if you tend to be in between mesures at waist.
