Tuning Questions using 2g Maf

[CarPsyco84]

Ok, to clarify, the car runs awsome at WOT 30psi... its litterally when I'm not making boost when it runs like shit. My questions I guess are, can the 2g Maf be too close to the turbo? If the blow off valve is tight (not like a stock one where its open under vacuum) could that cause air flow issues with the Maf? Its currently vented to atmosphere, but that isn't the issue here, because I put a hose back into the intake from the BOV and it still had issues. It just seems like if you get the turbo spinning a lil bit, it causes the Maf to read higher hz than it should... Its hard to explain, but if theres some tricks to a 2g maf in a 1g I'm all ears.
