a manual trans would have made you a LOT faster. I think I've even seen video's on utube of the difference (which is several car lengths).
So since your dumb enough too start with a slow vehicle (and want more speed out of it), you live with that slow vehicle. With all the mods I've done you'd be as fast as I was stock..
Edit: Here's that link too that race --->
I'd like too see what a 6-port Automatic 6-speed accelerates like compared too a normal 6-speed.
