I ran a 14.2 @95mph my first time out (sorry don't remember my 1/8th time) with basically the same as yours minus fmic. That was with a 2.2 60 ft. Hopefully the next time I go out I'll have the FMIC and VLSD in which should put me the 13's me thinks....even if I'm a crappy driver!
Suggestions? fix your tranny, get an LSD of some sort, and better tires. Those should all help.
What rpm were you launching at?
