Turbo Shuffle

[md4etal]

Another question is do the turbos have a compressor recirculation valve.  It
sounds like the system is near the surge limit and the two are getting into
a harmonic.

Porsche and even lowly Chrysler had a bypass valve that would allow the
compressor inlet and outlet be connected so that the compressor was not
"operating" under a low flow condition.
