My BOV is sticking open, whats a good cleaning agent to use? I have brake cleaner, engine cleaner, WD40 etc......

I'm kind of scared that I tuned my car with this problem, I dont know if it was leaking while I was pulling on the dyno. Car still runs good though.

I have heard that the new hks ssqv design does it but especially the blitz one. It;s because of the design where the valve opening is directly the piping instead of chambered then valve. The new design is supposedly made for sound which is maximized with the valve facing the piping
