Turbo surge.

That's what causes the boost gauge needle to flutter.


Or a defective gauge, kinked line, etc.

I wouldn't think with the ATS housing you would get turbo surge. I have a a WW and see boost bouncing around a bit above 18-19 psi but don't hear the surge sound.

This is a good you tube video for turbo surge:

Well my boost gauge flutters,it shouldn't be surge cause I'm running an ATS housing,I didn't use the line that come with it,I used a heavier duty line that we use on big trucks,and I guess the gauge is OK,but if I remember right,it's always done it.I can usually make 23 to 25 lbs. max boost.
