Still have the leak, car sounds like it's chewing itself up on first start 
. I torqued it properly and it didn't quite line up with the heads so I kept bolting it down harder until the manifold was properly seated, way more than 89in/lbs... Could that have caused the leak? I can't imagine getting it too tight would cause problems but this is the first time I've installed one. Are there thicker gaskets out there that might help the fitment issue?

If you didn't, I think you just found your problem.

. Thanks for pointing this out, that is probably my problem! No wonder it didn't fit perfectly when I installed it .Thanks!

You also shouldn't need loctite on any of those bolts. I strongly suggest you slow down and spend more time reading this forum, LS1tech and many of the install guides.

If you read one of my earlier remarks, I suggested the factory bolt heads cracked the underside of the FAST intake. Did you inspect the bottom of the intake carefully?

That is the next thing for me to check. The answer is no it isn't in tight, it's quite loose. What did you use to seal it? I've made sure to check everything else so that just might be the culprit, looks like I'll have to take it apart again .

I used Formagasket #2(white tube the sealer is a brown color). I put in on, then took a C-clamp (with a rag between the MAP and the clamp) and lightly clamped it down over night. Next morning came back and it was good and tight. Also is sensor safe

Thanks for the info! I'll take the whole thing apart and use the formagasket when I get some free time this week.

. Could the tps need to be adjusted? I'm going to look into a smoke machine to see if I can find some sort of vacuum leak, I've double checked everything that I can get at.

$%^$#@%^ that would suck. I'm getting really good at taking it out but I just want my baby to run right again. Could they destroy something while porting? The porting job didn't look very aggressive. Thanks for all of the advice!

I'll start taking it apart again tomorrow... Is it worth taking apart to check or should I just send it back and have them send a stock fast?
