Hey All,
I'm thinking my turbo has compressor surge pretty bad, however i am unfamiliar with what it actually sounds like. I can hear my actuator/turbo "blow off" louder than my HKS BOV. I have to really slam it for the BOV to chirp, otherwise its just a measly little sound....

How do i go about fixing compressor surge? Id really like to NOT kill my turbo/engine. Here are two videos i took. Hopefully you can hear the sound. This is my turbo not my bov.

My BoV has it's own dedicated vacuum straight up to the Intake Manifold, and the wastegate has it's own vacuum source straight to the nipple on the hotpipe.
