Installed diff bov, now possible compressor surge

[Perkul8r]

So i got a used Turbonetics Raptor bov and installed it on my car last night. I loosened the adjustable set screw on it cause it was set about all the way down. And i just retightened it a lil but. I am thinking maybe i went to far though. Because of the side exit exhaust i can usually hear the turbo spool down. And with the stock bov it was a nice and smooth spool. But now every now and then it when it spools down i can hear it fluttering. I was just wondering if this was compressor surge or not. i dont want it to screw something up. Thanks.
