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!

High hopes

Read that works best if used with premium fuel, have ran premium in it the whole time I've owned my jeep. It does actually work as advertised. More power across entire RPM range, has increased my mpg by only 2 though nut still an improvement.
