Greddy type s BOV not holding past 20psi or so

Which way is recommended? I've always heard recirc is best so you don't lose metered air.

Recirc if you are draw through.

This matters if you are running a draw through MAF. If running no MAF (ie MAP) then it doesn't matter. As per Forest Gump's post, it implies "Blow through" also does not matter.

When I switched from my Blitz system which was running a vent to atmo plus using the stock rec adapter and stock ecu the car ran fine. The stock BOV/rec adapter started the old hooting owl trick so I simply removed it and went pure vent to atmo and the car would stumble after it "blew off". I switched to a TurboXS Racing Bypass Valve [setup like the stock system] and the problem went away. I have since gone standalone ECU and MAP so it no longer matters.

Got a log of it on the street. Apparently happening at about 19psi as well. Showed up as single psi blip and I could hear the bov flutter. It was worse with more boost. BOV came in but the adapter won't be in until Friday.
