honestly, you have to be bad to miss shift at a point where a '95 auto tranny beats you... Even on a 240sx. Tom's focus' turbo'd, power is power. But the only advantage I see in autos is no (or almost) wheel splipage on start... which is really the only thing that on a FWD without LSD could make you lose.
Trust me, i know a lot about how auto trannies are made, even more in the 90's...
PS: If you want to win, just don't drop the clutch at 6000rpm and WOT right after, between 3000-3500 rpm launch and a lil' bit of time not at WOT for the car to catch up and you should be good.
