fCuk man.. my car is doing something similar.. is it normal for your BOV to be outputting black shit? my bov sits above one of the hoses for the intake and like the outlet releases the air onto it. I noticed that there is like a black gunky buildup on the hose that the BOV is blowing air onto.
anyhow, i change my MAF and i didn't get any results. I tightened teh spring on my BOV and it started to drive a little better, but not noticeably. I didn't get the problem when i was in neutral, but now i get the problem in neutral too. i think i'm about to just take my car to Blue Stage and let them work on it, cuz it's starting to drive me nuts. i already changed spark plugs, did an oil change, change the oil pan gasket (cuz i thought maybe it was losing oil pressure cuz there was a small leak around the oil pan), tested a good maf, cleaned out my intake filter.. i dunno.. i don't have the time to work on the car anymore.. and i'm trying to get rid of it too.. *sigh.. anyways, anyone find out what other fixes there are?

Greddy BOV
HKS turbo timer
Fujitsubo cat back Exhaust
Blitz intake
Defi Boost Gauge
The boost gauge acts a little wierd, so i'm thinking my BOV might be bad.. when i accelerate, my needle should be doing nothing but going up, but i watch it take dips and it goes back down.. so i'm thinking it might be a vacuum leak.. my initial assumption is that the spring in my BOV is broke or has lost it's tension.. *shrug.. thinking about restoring original hot pipe and getting rid of my BOV..
