My feeling exactly, and that's WITH the Ford tune. It seemed to help matters for a bit at first, maybe, but not much any more. I almost never use D. I wonder if I should un-install it, then try it again? I would buy a different tune if I was positive it would fix things for good. I never even...
I've had mine out on 2, 3-week trips up to the Sierras. After the first trip, I sold the lousy Hankook tires and put on KO2s like I had on my Tacoma. It also has Firestone air bags in the back and the FP tune.
