In this case, "gauge" is important though: it indicates that the value
is a delta (the difference between MP and ambient pressure) and not an
absolute pressure.  Do you not want this value?  That is what is
normally termed "boost" when one talks about super/turbochargers.

Yeah, but that's a bug.  There is only one manifold pressure.  Surely
you don't want *both* "mp-inhg" and "supercharger-output-inhg", which
mean exactly the same thing.

So it sounds to me like all you wanted was "mp-inhg" in the first
place...  I'll just chuck the new properties.
