Hks

On low boost it flutters, but after like 4psi it will make a loud high pitched sound, I love it. It doesn't seem like anything is wrong, if it flutters at higher boost some of the lines might be hooked up wrong, it happened to me.
later

maybe its more noticeable cause its a short ram intake. i really dont like it though so if i can make it go away id like to.

Tighten the spring down . You really dont want it to open much until your in the boost range. You will get less flutter. Flutter is normal though. You should here the hks on my car. :evil:

put stock air box back on, alot less flutter (because it dampens the noise alot better)

my BOV is cranked all the way down pretty much and it lets off at about 10 under vacuum, but anything lower than that and you dont hear a thing. Anything over 10 vacuum and that baby screams!
