You know, I was thinking about that while I wrote my response awhile ago.
Since the turbocharger's turbine is a throttling heat pump, we would see
the maximum output from that turbine when the temp delta across that
turbine is a maximum. If you were to monitor EGTs both before and after
the turbo, you could then watch for the conditions that make that delta a
maximum, and tune towards that. You should keep in mind though that we
would also want to maximize the pressure delta too. Maybe we should
have pressure taps before and after the turbo as well... :-)
