I need help badly with my galant vr4. All was well until I did a quick WOT run for some tuning and the car did well until I let off.

Started idling and cruising really horribly as if it had a vacuum leak. Found a small one at the EGR blockoff that I fixed but the problem still remained. It doesn't want to idle at all, runs stupid lean at idle, and doesn't want to cruise worth a damn at all.

BUT the car runs perfectly fine under boost, what gives?

HELP!
 
Send me a log of what's happening with it later, I'll be on AIM in 10-15 minutes.
