like EVERYONE else said... ur a bit laggy on the turbo with LTs
(I am experiencing this myself, b4 i didnt believe it was but after seeing vids - mine sux with LTs)
... also, like ppl say ur injectors will be way too small. i am using 60lbs on a T67 which seems fine.

i just ordered MAC ORY pipe that mates up to the stock manifolds. i'll be heatwrapping that as well.. INSTABOOST! lol

My friend 1320 has been down this exact road, he switched back to manifolds and the car was better.

Did you guys have the cam I have? That cam pushes a LOT of extra air that a stock one does not.... Ya know, I have the headers off right now... **** I may as well ****** put the stock manifolds on.... damn it.

The spool times you noted above are not that good. Probably has something to do with the cam, but wrapping the exhaust will make a big difference. I could usually get mine to 5PSI by 3400RPM in 1st, 3000 in 2nd, and 2.5K or lower in 3rd-6th.

BTW, 36lb/hr injectors are too small. I maxed out 42's with less cam then you and only 5PSI. I was running (and still run) MotoTron 60's. That was with a Racetronix pump, hotwire, and a return fuel system referenced to 60PSI.
what y pipe did u use? i will be using the MAC 2 1/2 " to 3" collector y pipe that matches up to the stock manifolds.

stock manifolds FTW, you won't regret it. If you can get them ceramic coated, even better.
