So this has been happening for a month or so now, when I’m in vacuum, between 2-10, I hear this loud whistle like the bypass valve going off. I’m not sure where the vacuum leak would be coming from though. Would it be coming from that Bypass Solenoid on the Intake Manifold or would it be further back? My Hot Side Charge Pipe is on really good so it’s not coming from that. Any ideas?
