i installed a greddy type s bov on my car today where the stock bov was. the hose that i used is about 7 '' long. the car runs fine but i still hear that fluttering sound from the turbocharger in the accordian hose area. the bov is on it's hardest setting it tightened the nut as much as i could. i'm running 9LBS of boost right now. could this fluttering be because the hose i used on the bov is too long or should i try a softer setting on the bov?
