ok so i have a greddy type rs bov on my turbo sunfire under low boost i hear compressor surge and around 9 psi i hear the bov then compressor surge after. is it tightend too tight? should i adjust the screw in or out? any ideas? also i am running the fmu,boost gauge and bov off the same vacuum is this a bad idea?

Are you sure its compressor surge? The greddy bov's are pretty good preventing surge, try adjusting it down. But pull your compressor outlet off and see if theres alot of black residue and feel the shaft as well.

The vacume hooked up that way isnt hurting anything, but yes it wouyld be best for each to have its own vacume like using a vacume manifold.

how about a strip with a bunch of individual valves? like this one i have?

That is a vacuum manifold....

sweet do i leave one end of the vacuum line looped like that with the valve open?
