Mike asks;

>The car seemed a little slugish compared to what I remember it being,
but then again I'm used to my Stage II TQ, so it could be my
imagination.  The car runs great still, but is there a high altitude
adjustment that should be performed on it?<

My Bentley manual specifies that normal tuneup adjustments be
performed at the primary altitude of operation (probably timing and
idle speed only).  The control pressure regulator and the lambda
control system should provide compensation for altitude.  At any rate
the air up there has 25 to 30% less oxygen, therefore you get 25 to
30% less horsepower.  A big difference without a turbo and a waste-
gate to regulate the intake manifold pressure (and therefore oxygen).
When I last went skiing in Colorado I noticed that all of the tour
busses there were powered by turbo diesels.  I rarely see that here in
Massachusetts.
