There is the ECU, relief valve, Blow off valve and throttle body.
The ECU send a 12V signal to the relief valve, by doing that the relief valve open and send pressure to the BOV valve and that keep it shut so pressure is built in the intake chamber, When the ECU want to relief the pressure it cut the 12 V signal to the relief valve by doing that it bring vaccum to the BOV and that make it open so it relief the pressure. The BOV opening depand on the vaccum pressure from the throttle body so the more vaccum you have the more oppening you get from the BOV.
The BOV is not ajustable so it is really the ECU via a pressure sensor that control the pressure.
