Superchips Flashpaq F5 Tuner Reviews


It works

Reviewed By Ray Y (Colorado Springs, CO) Reviewed for a 2005 Jeep Wrangler —9/13/2017 8:30 PM

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.
