I was happy with the product. It gave me extra torque and horse power. Even though I was hoping it would be more power, it was still a big difference.

I installed the tuner on my '05 Jeep Wrangler using the mileage option. I can't tell any difference in performance, but I did gain 3 MPG. I started at 15 MPG and now I get 18 MPG. That is a 20% improvement.
