Why does this happen when I spool the turbo
Hey Whats up, Im running a 99 gsr with a greddy 18G turbo. I recently got some work done on my clutch. I installed a 6 puck act heavy duty w/ 12lb flywheel. I was wondering if my boosting is running wierd or do I need to get a tuning? Whats happening is the boosting sounds like it whistles and it slightly lags before max psi. I remember it would spool up a lot smoother. Also, I when using hardly any turbo my bov sounds strange too but only lately. It makes a noise that sputters air more then one even release of air? If i hit the gas hard and get real high in rpm's it sounds nice? any thoughts?

Re: Why does this happen when I spool the turbo (KeithGSR)
does it sound like fluttering when the bov goes off?
cuz then it sounds like compressor surge, and the most likely culprit i can think of is a bad vac source or line to the bov. make sure it's connected tightly and not leaking at either end.

Re: (Boostfedb18c1)
Yeah there is a whole mess of tri split connections. Does one vacuum manifold replace this? Another thing I just noticed is the turbo doesnt really boost at all in first gear....too much pressure...boost leak? what do you think? I know I need to replace my spark plugs...because they gone bad...but is that going to fix the turbo spooling?
