Superchips Flashpaq Tuner With Locksmith Kits
The much-anticipated Superchips Flashpaq tuner for 2019-22 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 (P/N 2849-F) 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 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 the 'Remember Last Setting' feature that allows your truck to remember your Start Stop and Drive Mode settings every time you start your truck. Superchips 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 cannot be reversed. If VIN lock and ECM Unlock has been completed, device is non-returnable.

Mr. Gasket Ultra-Seal Exhaust Gaskets
Mr. Gasket Ultra-Seal exhaust gaskets are designed and constructed to improve the sealing of exhaust header flanges. Unlike standard exhaust gasket material, Ultra-Seal gaskets incorporate a graphite-impregnated facing and a steel-expanded metal core that reinforces and increases their tensile strength.

Ultra-Seal gaskets are available for a wide range of port styles and sizes. Additional features and benefits: * Expanded steel core provides stability and maximum torque retention to eliminate gasket failure * Graphite facing provides excellent heat resistance and thermal conductivity to transfer heat away from the cylinder head * High-recovery material allows header or manifold flange to stay sealed if flange loses clamp-load * Can be trimmed for modified port applications * Designed for OE replacement, high performance street, drag race, road racing, and oval track use
