Compresser surge and BOV adjustment question...

[Onizuka]

Right now im running a S15 T28 at 7 psi and I get alot of compressor surge durring shifting, especially at anything below 4 psi or so. Anybody else have this problem? I'm running a very clean used blitz supersound, and I have no manual for it. Im assuming turning the allen screw counter clockwise will alot it to work properly at low PSI, but I was wondering if anyone else who has had experience with this model can conferm this.

Thanks for any help I can get

Ball bearing turbos make compressor surge regularily. Its normal, which is why ball bearing turbos can take it much better than journal bearing turbos.
