I was running my car perfectly fine today, then when i came home i ran it a little hard and then a problem started with it that i cannot figure out. i have my greddy EBC set to 10psi and when i gunned it it only went to 7psi and made this weird *** fluttering sound when the bov sounded. i first thought that a charge pipe came loose, but i checked all of those and they were fine. so, does anyone have any idea why it would only boost to 7psi now on the 10psi setting and why it is makign that weird fluttering sound for the bov when i shift?

 

well i feel like an idiot now. i had a vacuum leak b/c one of my lines was loose. problem fixed now....
