wg set at 9psi. I havent realy gotten of it cuz my AEM's not tuned yet but low boost it swooshes with a wistle sound and at highter boost it flutters. (comp. surg?)
there's a wrieup that explains that sort of thing, you're probably just not running enough boost for your bov is all.
if it's adjustable you could loosen it off a bit.
its in the same spot iv seen hunreds of others at, about 10-12" from the throtle body. Its labled by the ajuster witch ways soft and hard.... with arrows and everything..
Boost pressure wont matter with the Type S BOV, as said before, check the BOV for how tight the spring is and if not then check the vacuum line powering it, you might have a leak.
