Not 10's but mid 11's should be obtainable with some tuning adjustments and the addition of the Gen V/Northstar setup, I would consider my current tune "conservative". Checking the Fiero forum I don't see any 3800 M90's under 11 seconds in a Fiero, most are 12/13's. I see a couple of 10 second 3800 turbo Fiero's, and one guy is flirting with 9's.
The latest Fiero 1/4 mile list is here, http://www.fiero.nl/forum/Forum1/HTML/070670.html
Thanks for the heads up on the mirror, I like it....
