Why would you possibly want to know this type of arcanum?  A turbodiesel
engine typically produces far more boost pressure than the engine can
possibly match with an appropriate level of fuel...whether at sea level or
at the highest mountain tops.  The wastegate kicks in at a given pre-set
pressure, no matter the elevation. [puzzled]
