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.

We are working on updating the extreme tune to work better with these new calibrations, so far testing is going well, keep an eye out for an update.

I am experiencing the same Extreme Tune limitation but the speed limit is 60 mph. I had our local Diablosport authorized dealer update my unit to the latest release.

Any thoughts or help.
