Does one need to run the 12 minute adaption tune when changing the speed adjust? My speedo is off about 3-4 MPH at a -5.1. It came with the Tripp Tune Map, so I left it as it was.
I have a couple of GPS apps and found the difference. I'd like the odometer to be correct, too.
Thanks!!
$ell i just don't want a ticket by pushing the limit. 72 miles per hour here in Oklahoma they will not $uck with you. Anything over depends on the trooper.
