How do I get my car to idle?

[OneFastEclipse]

I installed a bunch of things at one time, (Turbo, Manifold, Exhaust, injectors, fuel pump, etc.) and now my car don't want to idle for shit. I put in 550cc injectors and did the correction on the SAFC and my datalogger shows that the car is running perfect, right around 0%. Yet when the car is at idle it sputters and sometimes wants to stall. If I turn on the defrost it will stall. I checked pretty much everything, checked for boost leaks by pressurizing the lines, I have none, replaced the spark plugs and wires, did a compression test and got 190, 180, 190, 180. Check for vacum leaks, all seems fine. What could be causing this? I think my turbo to manifold gasket might not be sealing all the way so I ordered a copper one. Could a leak there cause the car to idle like crap? Everything is great when driving, it's just the idle. Thanks alot guys!

It has to be a vaccum leak somewhere. Maybe a gasket got bent while you were tightening it back up. Happened to me at the throttle body and I didn't even know until I went back and checked all the gaskets.

Wouldn't a vaccum leak be obvious when I presurrized the intercooler piping? I thought I would hear it hissing from wherever it could be.

Kinda easy question, did you adjust the biss screw at all? Is it still in there?

I read the write up on adjusting that and it says I need a scan tool. Can't I just let the car idle and adjust that to see if it gets any better without the scan tool? Is there a way I could use my pocket logger instead? Thanks!

anyone?

you just screw the screw in to make idle go down and ut to where it rises it im guessing its idling at like 500 rpms and when you kick on the defrost it does down to 450 and stalls
