It might but I doubt it. I know its heavy but its not THAT heavy. I'm a skinny gringo and I can lift it. lol
I was getting 9's before the programmer, then 8.5-9 with the canned tunes (all three, but with lvl 1 & 3 modified). I've also been getting the same numbers with Bill's performance tune. I was kinda hoping for the occasional 7 but I guess that the "no replacement for displacement" hold true for my truck.
Price I pay for having the 4.6 I guess. Not that I dont like Bills programming, I definitely like how it shifts. Glad the loud pipes and other stuff scare away most of the ricers over here.
