I'm not so sure about that the flat power curve on top indicates that the turbos are under utilized. Isn't this what you would expect when the turbos spin at full capacity and as rpm grow and they no longer can support peak pressure the rpm linear power growth by more combustion cycles per time unit is equalized by the linear inability of the turbos to support the air volume resulting in the same volume of fuel per time unit and a flat power curve?
