And, jrthomas15, I think JWBFX4 answered you probably better than I would have done! (In fewer words)!
JWBFX4, you are absolutely right in every point. (You seemed to be asking a bit of a question when you mentioned "shift points", but I'm sure if the gear setting is wrong, the net result is going to be less than optimal, in terms of power or economy. Although, Ford DOES engineer these settings to give a balance between acceptable power and economy. Any change is going to sacrifice one of them. The 35" tires are going to hurt acceleration with stock gears.)
I suppose having the wrong GR setting programmed COULD be a bit like "two wrongs making a 'right'", but that's not the way I'd tune my truck
Sorry, JWB, I just couldn't help adding some thoughts. Your post was dead on!
