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?
