txsilverado, looking at the hypertech file, when hitting the towhaul mode, it actually lowers your rpm wot shift. maybe thats what wrong on your truck.
i have no clue whats up with it...i didnt do the tune, and when i went to the guy who tuned it i figured out the tuner was taken out by a fire. allan hooked up to it at the last houston g2g and figured out that the pcm was locked somewhere along the line . im not too worried about it. this summer i plan to get it reflashed at the dealor and drive up to allan and get a good tune.
