Speedo recalibration?

[Steve Krusich]

I unsuccessfully checked the archives and the SCT website and could not find out how to re-calibrate the speedo on my 07 4.0 SportTrac. I recall a post many months ago on the subject but I cannot find it. If it is not too troublesome, I would greatly appreciate some help. Thanks.

Determine rear axle ratio and tire RPM per mile.

Thank you so much for the info. I did not see the Gen 2 Sport Tracs on the list?

Above adjustments are shown with your 2007 V6 Trac on SCT's main site. If in doubt, contact your tuner, hopefully Torrie @ FPN. :supercool:

I have used Torrie for years. Thanks again.
