Turbo surge doesn't occur when sitting still in your driveway. Start a new thread

I did start a new thread

And who said anything about sitting still. Pretty much the same situation as OP.

Where does the surge exit, making that sound?

Surge is a function of the compressor wheel. It doesn't 'exit' anywhere
