"Tuner is awesome. Speedo calibration is great, it's about time someone offered this tool. Performance tunes eliminate throttle lag, sharpen shifts, and greatly enhance launch. Unexpected surprise-performance tunes also increase MPG's! I love it, my rig is quicker than it was stock even with the added weight of aftermarket skids all around, and 32" tires!" —Robert G from Rolling Meadows, IL bought a Superchips Flashpaq Tuner for a 2008 Jeep Grand Cherokee.
