You're suffering from a relative lack of available oxygen per intake
stroke.  High altitude is where boosted engines excel, since they oversupply
oxygen under boost, and thus tend to lose less power at elevation.  You
could add a turbo or nitrous oxide, but other than that, you're at the mercy
of the mountain gods--sorry.
