nice upgrade for a 3.7 jeep!
I bought this for my 06 jeep grand cherokee with the 3.7 V6. it has a 2 in lift and bigger tires (31's, i didnt want to go too big since its my daily). i bought the programmer mainly for tire size calibration for my speedometer, but i was pleasantly surprised by the performance increase from the tunes. great power increase across the RPM range, throttle response is instant (i also have an injen cold air intake), its no race car but its a nice addition. MPG's increased also. only con is price
Best Programmer Ever!!!!!!
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!
