Sometimes I wished it had a proper tranny. I wouldn't lose so much HP through it. The next thing i'm going to have done to it is to have the heads ported and polished and have the stock cams replaced with a 212x cam. Then we will try it again.

i can only assume that since you have the automatic, even though you have a superchips, i am probably putting down the same amount of power (+/- a bit tho)

You probably are. The tranny in my truck is freakin' huge. But it's pretty tough for an aoutomatic.
Everything you see in the dyno run is with the overdrive off. My truck will run 115 without the overdrive. It's sitting on 5,500 RPM's though.

yeah theoretically with my gear ratios, my truck will top out at like 180 too bad 212 hp won't get me anywhere near that close

when i put on my stage 1 clutch, i should be able to make those numbers, right now i think mine is starting to slip a little bit
