Best Programmer Ever!!!!!!

Reviewed By JOHN R (Lamoille, NV) Reviewed for a 2006 Jeep Grand Cherokee —6/9/2016 5:37 PM

I recently purchased the 2006 jeep used with 123,000 miles. I was getting 14.5 MPG. TERRIBLE!!So I looked into chips and decided on the Traildash2. I was I little concerned about about the price of $499.00. Despite my concerns I went ahead and bought it anyway. The down loading and programming process is a little challenging but after a number of phone calls to Superchips I got it all done. I am now getting 22 MPG around town. It also fixed my inaccurate speedometer.I couldn't be more pleased!
