As the first ever pre-calibrated performance tuner to hit the market for 2019-2020 Chevrolet Silverado and GMC Sierra 1500 trucks, the all-new Flashpaq 2847-S has made quite the splash with consumers. Built specifically for the 5.3L and 6.2L V8 trucks, this little device offers total control over the Chevy trucks performance features with the ability to add as much as 45-horsepower* in the midrange, with increased torque for towing, improved fuel mileage and of course the ability to adjust factory settings like speed limiters, rev limiters and even tire size for speedo calibration after larger tires are installed. The Flashpaq even gives owners the ability to disable the factory Auto Start Stop system, remember your last drive mode if you prefer to daily in Sport Mode, and even turn off the factory’s cylinder deactivation mode by disabling Active Fuel Management.

While the device was well rounded and offered exactly what Silverado owners were looking for at launch, our calibrations team hasn’t just taken a month off after accomplishing such a feat. No, with a little more head scratching and breaking down of the factory’s computer code, Flashpaq for 2019-220 GM Gas Truck now offers a built-in throttle booster setting allowing the end user complete control over their driving experience. With the ability to fine tune pedal feel from 0-50% over stock, you can now use Flashpaq to set that pedal feel exactly how you like it by modifying the our pre-calibrated tune files within the device.
