Unrealistic engine behavior at high altitudes

Is this the DUKE 60 &A60??
Looking for the POH

@meh1951 it's the B60 and Grand Duke. (B60 with aftermarket aero mods) I think most parts of that POH apply but the speeds and performance charts will be off, especially for the Grand Duke.

@Hawkeye That's interesting, are you at full throttle or setting the MAP? And I have a full fuel load but only 50 lbs of cargo and 120 lbs in the Pilot seat, so I can see the speed faster, but the fuel burn is much higher as well. And -40C is only 1 degree off standard day.

@lilycrose I’m using my throttle to set the power to the proper setting within the power charts. I’m demonstrating that the turbocharger is overperforming at high altitudes because when the proper power settings are achieved, the aircraft behaves as expected per the manual. TLDR: Turbocharger issue, not Flight Model Issue.
