Yes, in tow/haul the whole trip pulling the trailer from GA to NC. Not in tow/haul this morning on the way to work and not towing anything.

Tire size is 265/70/17 and adjusted with the flashpaq. Checked the speedo against a GPS and was within 1-2 at 75 MPH.

No the trans is not tuned. Only thing I have used the flashpaq for is adjusting the tire size. I've had far too many problems with it to trust it to do anything else besides tire size.
