Adam, nice project review. You have a solution and hopefully happy customer(s). Good work.

There is a phenomena in the turbo world called compressor air noise. It's not discussed in the popular books on turbo applications. Some argue it's a soft SURGE, but surge none the less, as such the engine should be matched to the right of this region. Others call it aerodynamic instability and if it doesn't manifest itself in the actual application, as demonstrated by road testing, there is no harm. The problem is you have just introduced some very challenging NEW road conditions. It's often present in compressors designed for broad flow range needed of variable power turbine applications, just like yours. I suspect this compressor has it.
