Do agree, keep it on the track.

Correcting my original post.
Higher altitude means less pressure and hence less dense air. Less pressure means the turbo has to spin faster to achieve the same pressure ratio at sea level and also the FMIC is less efficient at cooling. How much power loss for a FI engine at altitude depends on how efficient the turbo or supercharger and FMIC are operating.
