Where Should I Look?

Installed my ported blower and northstar last night. It's running great except theres a vac leak somewhere (ugh). Everything looks good, it's all connected, seals seem good, anything that needed to be capped off is capped off...I'm brakin out the brake cleaner later to start spaying around. It was perfectly fine at first, then I drove around a bit, got into boost, came back and popped the hood, suddenly its idling like **** again. First check last night I couldn't find one. It's been idling like **** forever, and it finally seemed fixed when I left, then I drive around for 20 minutes and it's back. Ideas?

Edit: The PCM was obviously unplugged for a good 5 hours so **** was reset till I drove it a bit and it relearned, maybe it's something in the tune?

That was my guess too, the wierd thing is its been doing this ****ed up idle since fall. Oh and as far as that engine movement thing from that other thread, got the mounts check out. Perfect. I don't get it.

Where did you get a ported blower?

I think mine's doing the same thing, when i'm sitting somewhere idling with it in gear it just bounces between like 600-800 rpm. Pretty damn annoying. That and i've noticed at WOT it won't stay @ full boost.

Yeah that's a vac leak for sure. And mini I bought it off a friend.
