Change in engine power as altitude increases in GA planes

FYI, the report that requested those changes for turbocharged aircraft in order to avoid leaning them as IRL:

Inaccurate Mixture Behavior on Turbocharged Piston Engines

There appears to be a bug in the core mixture logic for turbocharged piston engines in MSFS. In real-life, a turbocharged fuel-injected engine should be able to climb with full-rich fuel mixture all the way to the critical altitude for the turbocharger with no loss of power or engine performance. The turbocharger can compensate for lower air pressure with altitude by compressing more air into the intake manifold and allowing the engine to operate with the same manifold pressure as it would at se…
