Hello everyone, recently turboed the xB. Running a descendent kit with a Tial-Q. I'm not recirculating, I'm venting to atmosphere. I have my BOV tapped into the Vibrant vacuum block and it's not blowing off, it needs a main vacuum source. So my question is where did you guys tap to get the main source when venting to atmosphere.
P.S. I removed the air box and rain a pipe from the IC to the TB.
