Any way around running rich with the bov releasing in the atmosphere? Or is the only fix to recirculate the air?

here are my mods..

cast turbonetics manifold w/ tial wastegate
3'' turbo back
apexi fmic w/ blitz bov(atmosphere)
brand new rebuilt engin with arp's, eliminated balance shaft, new pistons/rods

have apexi s-afcII and 660 cc's but not installed due to no afpr , also have walbro 255

Yaeh you can get the gm 3" mas and maf translator. With that you can tune it and not have any problems with running rich between shifts. Otherwise you will run rich always! Because the ecu thinks there is more air coming in so sends more fuel. With that airing being vented out the extra fuel has no air to mix with. But a recirculating kit and you wont have any problems. Or the gm mas and maft. That would cost around 300 or so though i beleive.
 
Even the MAF-T though likes the recirculated air though.

Could you explain this? If the MAFT is in blow through how would it like the extra air? It would see it but if it is not there there should be no difference? Some people argue that the turbo will spool faster with a Recirc. But why would a MAFT in blow through like one better then the other?
