heres a little combo background, 91 gt auto ,3500 stall,4.10 rear,306, gt40 heads,was told it has an e cam ,equal length shorties, x pipe,dumped flows,performer intake, 75 mm t-body and spacer,coldair in the fender,24lb inj. ,c&l 73mm mass air.
i just got the car,so its not pretty lol! and am hoping to hit the track this week.
ive got the tps set at .96,14* tim. was wondering about fuel pressure?
is stock spec ok to start with,wasnt sure since the bigger inj.
any advice is appreciated.it would be nice to hit a 12.anything what do you think?

I would start between 38 and 39...
Bump it up from there and watch the mph on your slips....
Keep going up til' it slows down is what I've heard most guys do...

Mine is set at 38 and the computer takes over from there...
