I have had this problem for a while and have tryed a bunch of things to fix this situation and nothing is working.

I have had a greddy type S bov on my car for about 6months, it worked great,sounded great etc. , Well all of a sudden my car started and still makes this fluttering noise/ compressor surge sound instead of the usual greddy high pitched noise.

It does it all the time, part throttle or high throttle. Here are some things i have already tried:

adjusting greddy bov
checking all hoses to bov and boost controller
tryed hooking up the lower fitting on the greddy bov
bought a brand new greddy bov in hopes mine was broken
switched back to a 1g bov

None of those things helped, its starting to get frustrating. The only thing i changed was i switched boost controllers w/ my friend ( both are hallman bc's), shortly after i swithed bc's this situation happened.

But i did however un-hook the boost controller from the line that it intersects w/ the line ran off the bov to intake manifold. And w/ the bc un hooked it still has this comp surge sound so i dont think its the boost controller. Any help would be apreciated! thanks
