AHHH! that would make sense what would i half to do to fix it. its on my cold pipe and the moment and i did notice after i did switch the turbos that i got a rather large amount of compresser surge.

Re-circulate it back to the intake tract, tighten the BOV, get better BOV that doesnt dump air too fast or just not run a BOV...your choice.

You should be able to just tighten it. I hated my SSQ but they're actually one of the better BOV out there for MAF'd engines since they dont blow off to quickly if adjusted properly (if they're not leaking). Also, you can get a recirculate kit with it...which should fix your issue if tightening it doesnt help.

I adjusted my idler control valve. It worked for me and car idles fine. I just wouldn't play with it too much. Also i don't think its recommend but it worked fine for me.
