vacuum leak anyone?
 
Ok, so I have this slight problem. The car pulls like a banshee, starts, and runs. When I let off the gas after the boost comes on, something happens, almost like the turbos don't know what to do, like they're confused. It kinda shudders and heasitates and stuff. Before I go yanking all the damn lines and replacing them, I thought maybe someone would know what or where my problem is. Is the bad line in the rats nest or on the turbos themselves? Thanks in advance for the help.

Check charge relief valve and bypass valve control lines - sounds like the turbos are surging.

I was told by someone that they thought the problem would lie in the rats nest. Not sure how likely though. They spool great and pull like mad. But yeah I don't know if they're surging or not. I plan on putting a new bov on my intercooler piping, so I will have to eliminate the stock one correct? I'll check the lines from the CRV and BOV though. Anything else would be most helpful.

Stuck wastegate? Mine did this for a while. It would boost fine once, then the exhaust would be very loud and no (slow) boost the next time I floored it. The wastegate actuator was sticking. Check it out, if this sounds familiar.

I'll check that out too. It seems to be fine every time I floor it though. Hmm...quite interesting
