Greddy Type S BOV question help!
hey guys I was wondering if you guys can help me out. I recently installed a greddy type s bov with the recerculation kit on my 04 sti and everything seems to be clamped down pretty good. My question is now when accelerating when I reach 3k and gas it up anymore there's a mouse like sound that keeps on getting higher. What's going on? I noticed there's two vacuum lines and I didn't plug the one on the left. I capped that one. What could it be do any of you guys have any ideas? any help would be greatly appreciated.

just go back over everything again and make sure its clamped down, that may be obvious but a leak is the only thing that could cause that sound. Also how tight do you have the bov, maybe its opening under boost. Also dont worry about that second vac piece, either leave it uncapped to get the little whistle noise that the greddy bov is known for or leave it capped off like you have it.
