Superchips Flashpaq GM Diesel

The Flashpaq performance tuner is the best selling handheld tuner in the world. The success of the tuner is due to its quality, innovation and performance results. Superchips tuners plug directly into your vehicle and read the stock calibration stored in your vehicle. A stock calibration is the set of fuel, spark and transmission settings that the dealer installed in your vehicle at the time of sale. After reading this file and saving it to your Superchips tuner, the handheld device then downloads the Superchips tune to your vehicle. All engine and vehicle operations work exactly the same, except your engine willnow work more efficiently - which means more power, more torque and better mileage.
