Thanks for the retune. Softened up the shift points, and made some laps. Just a stock 4.8 with a shift kit, fans and stock tires.

I went from Houston to Brownsville on one tank, and there was a little past half when I arrived. 35psi up front and 30 in the rear. Flat land, just over passes for hills, two people, luggage, and a yappy dog. I was already getting great gas mileage 20-22mpg at 75-80, so on this trip, I did 85 the whole trip. I got the same gas mileage, with no changes. I slowed down for the small towns, but other than that I was standing on 85 the whole way. Not one cop on the way here . . . . it was really nice.

Thanks again for your time.
