you can route a BOV back into the inlet of the turbo sometimes
as for wat you want, MAF system meter flow PRE TURBO, so this means it is at standard atmospheric pressure. that being said, if you use a BOV and vent it, metered air will be lost and your AFR will be all over when you let off the gas
MAP systems meter manifold pressure as well, which is able to adjust for the fact that the BOV vents.....BUT the benefits to running a rerouted system are great for Dailys
now you can get BOVs to run just fine on the street, but from the motors i have built, rerouting is always good streetable fun
only real thing is the sound from a BOV, which seems to be why people buy them so much
