Default loud turbo

ok so i have finally got my car up and running again, it tends to like to eat spark plugs but a little bit of NGK iridiums and 8mm MSD wires helps a little also. DON'T GET BOSCH PLUGS THEY SUCK MY NUTS!!! :P but back to the subject.

i just got my full 3 inch exhaust piping done, custom 2.5inch IC pipes and new greddy BOV.

car is running good. but i can really hear my turbo. i mean it sounds like my claimant control is on its so loud and thats with the windows up. its seriously loud at 5lbs of boost, and thats also where my A/F ratio reads really rich. at about 7-8lbs of boost it hits fuel cut, BTW my wast gate is shimmed so im getting 11-12 lbs of boost "4 washers". i wanna say it sounds like a boost leak but i cant see anything wrong at all. and also on the IC pipe closest to the intercooler it has oil in it, is that ok? i was told a turbo seal is going out or is out. there is also oil in the accordion hose but not alot. im only throwing 1 code and that is 34 "abnormal turbo pressure, i want to say that was being thrown because the IC pipes kept blowing apart but that is fixed now. i also was thinking it may just be the BOV.

so what you all think it may be
