the reason its not a good idea to vent to the atmosphere, is because the mass air reads how much air being ingested in to the motor threw the turbo. when the bov dumps back into the intake track the metered air remain consistent with what the meter has already read. the ECU determines how much fuel to add dependent on how much air the mass air recognizes. when you dump to the atmosphere the ECU thinks that air that is being ejected from the intake track is actually being ingested into the motor and supplies a given amount of fuel to match the metered air. but that figure is now incorrect because the air is not going into the motor its going into the air, so now you have a disproportionate air/fuel ratio between shifts. i hope that made sense
