My 90 Firebird managed a few clean passes @ the track this past weekend. I did a best of a 12.85@110mph. I had a terrible 2.24 60' It is mainly due to my brakes not holding the boost. I need to install a porportioning valve b/c I swapped from drums to discs. I also got my calipers on wrong so theyre is still air in the system. I am launching of zero lbs of boost and supossedly only 11 lbs of boost max. I think my gauge is messed up. My 60' is w/ zero tirespin off the line. It spins towards the top end of 1st gear. I am running 110 octane mixed w/ 93 octane. Overall I am happy w/ the run b/c I know w/ my brakes fixed, some slicks and some more tuning I'll be deep into the 12's and possibly 11's.
I am using a 93 TT street chip w/ zero adjustments
