Your going to want to look into some head studs before you go any further, trust me. Two and a half years ago I ran a smarty on my truck on the dyno and make with the drag comp only 497, I put the smarty on level nine and make something like 460, then I put it on seven and ran 464. later that day we ran it on an 01 and he lost time in the quarter mile due to the fact that it didn't do away with the TM. I can't speak for the newer software, because I don't know how much it has changed.
