I hear a DSM blowoff valve

 

sounds like the bov isnt blowing off and the wastgate is clapping because of the backpressure.. thats the whole cha cha cha cha sound.. I got that exact sound when my bov wasnt blowing off and i had a internal gated turbo..

 

you mean, compressor surge?

 

Its compressor surge.

thats too high pitched for compressor surge, sounds like a tial bov to me
