im runnin the rs also. performs great but it tends to whistle. if you're lookin for a tried and trued bov, lean to the 50mm tial. my next setup will have one.

 

dont do it.

 

the turbo xs rfl bov is a piece of shit. I had 3 break on me. The trumpet will fall off and be lost, mine was 2 times. And than the actuall bov breaks, it will just start staying open when its not suppose to, and than when closed wont open. I have a greddy type rs now, and im happy with it.

 

have you adjusted it or just slapped it on...
