I have been told anywhere between 11 to 14.25%.. I set mine at 14.25(was told it was a GPS checked) and check it with my buddys new S-10 truck was 1 MPH off.... Close enough for me..... Somebody will have a GPS setting or something better......<img src=http://www.ezboard.com/intl/aenglish/images/emoticons/smile.gif ALT="
