Diosesmijuez has a '94 with a MAP sensor so he doesn't have to worry about recirculating it. He won't have any problems with running rich between shifts (I assume this is what was meant by the MAP not reading correctly -- that only occurs with AFM based cars).
There's another BOV thread that started yesterday that I've posted more info on.
Last pedantic note, it's a "blow off valve", not a "blow out valve".
