Take Off Power

Hi,
Question: What could be limiting the take off power for both engines? The indication is:
T/O for both engines (green); Fan %: 87 - 89; ITT: 750; TURB: 90%.
If I reduce thrust to CLB: Fan %: 93.8; Turb%: 94; ITT: 720;
Performance suffers -
Thanks for assistance

Local calibration?

Ok... there is no CLB setting on the ground... what are you talking about?

The only way these values would come up is if you had something that was not within the boundaries of the FADEC data. The TO N1 you posted is for a takeoff elevation above sea level. Since temperature and elevation are major factors in thrust settings, without knowing all of that I couldn't honestly track what happened. I know I have never seen this happen in any time I've flown the aircraft.
