How do i know if i have compressor surge? what does it sound like?
Right now i have the bottom line to atmosphere and when the bov goes off it lets out like a laser woosh sound immediately followed by a softer squeak/whistle sound

the softer squeek whistle noise could be compressor surge, almost like a soft duck or a choked out pigeon

That's exactly how my apexi twin chamber works. When i used to get compressor surge it kinda made a chu chu chu chu sound when you'd let off the throttle, just really fast though.

the chuc hu chu chu sound is compressor surge lol

for lower boost setup do you connect only the lower one or both of the nipples?

turboDA6

both, top for vac source, bottom to pre-throttle body, jus like the wg comes factory, like the nipple on the compressor housing. no vac source should go to the bottom one or else it wont blow off. only pre-throttle body positive pressure

Im thinking about buying a cheap knock off Greddy tyoe s but is it worth it? I might buy a used Real one.

i hear there almost the same, if you dont boost much, go for it. if your a power monster then get a real bov, not even a type s

I bought one of there BOV's too. They sent me a carbon fiber one though (I wanted a Purple one). I drilled a hole in the charge piping and JB Welded a brass fitting on there for the 2nd vac line.
