I've noticed a slight fluttering sound from the turbo when accelerating from a stop.. mainly heard in the low RPMs below 2500. I know I have an exhaust leak by the muffler, but I think I hear one in the engine bay too when the car is idling. Could a leak on the turbo manifold be causing this fluttering?
BOV problems?

Check your lines- you may have a pinch or leak.

Actually.. now that you guys mention it, the BOV doesn't quite blow off as loud as it used to. It kind of flutters too. Good call, I'll check all the lines first.
Well.. all the vacuum lines check out. For some reason though, the BOV still isn't blowing off the way it's supposed to. Even under WOT, when I let off the gas is flutters a bit then blows off just a little. Not sure what the deal is.. but it's gotta have something with the new 626 intake manifold, cuz it didn't do it before I installed the new mani.
video plz..also dont you have a greddy types.. i was reading something about those and valve or something fails in them..
I'll post a video tomorrow, and no it's not a Type S.. it's a HKS SSQV.
Although.. my next BOV is supposed to be a recirculated GReddy Type S..
im prob gunna go with this one http://www.youtube.com/user/ngrperformance
ngr makes it. look at the other vids of how it sounds.. exactly the same as the type s.. except apparently it doesnt leak..
Well.. it turned out to be a vacuum issue after all. I redid all the vacuum lines even though my gauge wasn't showing a leak, and after replacing them and redoing the routing on the newly installed 626 IM.. everything is fine again.
Thanks for your input guys, but I figured it out
