ok, realistic answers for you:
BOV is not for your turbo. it goes on your intercooler/IC piping. BOVs are also TMIC and FMIC specific, with adapters for both. vent to atmosphere combined with mass air flow sensor readings is not an ideal situation. when you vent, and hear that psssh, you actually losing all the air your MAF thinks is in the system. so for a slight moment, youre going to be running rich. theres VTA, hybrid (think 50/50), and recirculating. the reason why you SHOULD run a BOV is for higher boost pressure threshold. '02-'07 bpv's are steady for up to about 21psi, then they start to leak. aftermarket BOV's will run higher pressure than that. is that an '08 i see in your avatar? is that the vehicle you own? from what ive heard, the plastic looking bpv on the IC is only good for like 16lbs, in which case you SHOULD get a recirc bov.
personally, i run a Perrin recirc bov, for the above stated reasons of higher pressure threshold.
and hey, these are just my thoughts on this; if you want psssh, try a snorkus delete. or get a vta bov and dont listen to anyone here.
