Regarding the behavior of the turbochargers, you may be interested in this mod. Mixture Behavior Mod for Turbo Arrow, Seneca V, and Turbo Bonanza
It uses code to fudge the mixture behavior so that if you use a hardware lever you can treat that realistically (i.e.: full rich to critical altitude) and the software lever compensates to achieve that.
