Carenado Piper Seneca does not climb as it should

[WxMarc]

In a turbocharged aircraft, it should not be necessary to reduce mixture during the climb, should it? The Seneca V POH calls for full rich mixture until cruise. I’ve now flown a few turbocharged add-ons in the sim, and all of them exhibit a loss of engine power (and fuel flow) with altitude, which seems unrealistic. I’ve created a bug report for this:

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…
