Well, I noticed the BOV fluttering in between shifts, so I took it off. I was able to blow air straight through it. So this means the BOV is shot, right? Would you guys reccomend an open atmosphere BOV for the sound or a close looped system BOV? I want something fairly cheap, but durable. How bad is it on the turbo? I assume the surge could F it up pretty bad. Let me know guys. Thanks..
