I'm having issues with my bov. Why there is a bov and not a bypass valve is beyond me, especially since the previous owner put on a damn eBay bov. I just got the car a couple weeks ago. Here's my problems.
1. It almost sounds like it's constantly fluttering even just starting off and cruising, but less when giving it hard throttle, and then it excessively flutters after I let off the throttle if I built boost, and it will hold at a certain boost like 5psi and just make the flutter noise (surging).
2. When I first start the car it idles decent, go drive for a couple mins and come back and the idle is almost like it has a vacuum leak. I do have 90# injectors in the car (previous owner stupid move) and its tuned for 60% (should be getting soon)

But really I'm just trying to figure out the boost/blow off valve problem. The vac line to the bov is routed to a port in the driver side corner of engine bay next to firewall and the port says "A/C"
