M53-P2 High Altitude stall

[arnokm]

While flying high speed / high Altitude, the engine seems somewhat limited around lvl 655.

Even with a lot of air intake at high speed (1.6M..2.0M), with or without PC, the engine stalls.

I know IRL M2000-C should not fly that high, but is it a normal M53 behaviour to stall below lvl 660 ?

 

Many thanks to the RAZBAM Team for giving us such a deep simulation.
