How does a Mach auto compare vs. a 5 speed ?
If your talking the Mach auto vs the 5 speed it's about a half second slower. The problem with my auto is it needs a custom tune for the soft shifts of the tranny. At the track I may as well left it in "drive" since no matter where I shifted (5k ot 5.8k) my auto would bump the limiter and bog, nothing that can't be fixed but it's setup for the street not the strip.
