Your bov will blow off when you get anywhere from 5in/hg + up into boost. With you venting your bov, your car is expecting that air to be there. Yeah its only just a little bit of air but your car will easily go 10.0 off the scale rich just from that. I know you said you recirculated your bov but that is why your car is going rich like that. The reason it still did that while you recirculated it is cause your bov is probly crushed too tight and not opening at that low of boost level and the car still isnt seeing the air it should. Stop venting, recirculate the bov, and get an aftermarket one to hold that much boost, while still being able to open at a lower amount.
