U7164 EXTREME TUNE DOES NOT WORK
Posted: Wed Dec 21, 2011 10:46 am
Help I would really like to run the Extreme Tune!!!!! I have just installed the most recent 9r14 on my U7164, and loading the Extreme tune into my truck. With the Extreme tune installed, my truck will not allow me to accelerate faster than 45-50 MPH as if there is a governor on my motor, the pedal goes to the floor and does nothing. I am currently running the Performance tune and have no issues. I tried the Extreme tune with all 4 types of transmission settings and it still does the same thing. These are all preloaded factory tunes with no modifications or alterations. Ford Dealer did install a new flash to my truck about 3-4 weeks ago.
