Microsoft Flight Simulator’s turbocharger simulation has been significantly flawed for several generations.  This aircraft has a custom turbocharger that fixes nearly all of these issues, and is much more realistic, as a result.  To make these changes, the new “Input Event” system is used to intercept hardware and key-bindings for the mixture control axis.  Please make sure that your hardware bindings are using the Key Events, such as “K:MIXTURE1_DECR_SMALL”, or “K:MIXTURE1_SET” to set the mixture, and not setting either “A:GENERAL ENG MIXTURE LEVER POSITION:1”, or “B:FUEL_Mixture_1_Set”.
