Engine developing less power at takeoff

Normally I wait to the turbine temperature, oil pressure, N1, etc gets to normal configuration before pull throtle to 45% to equalize both
engines before start rolling to take off. This takes about 10 minutes. After the aircraft starts moving strait ahead, I increase to N1 65% to
reach 60 MPH, than gentle pull the throtle to 80% at 85PMH, finally 90% to get full power to takeoff.

A better way to do it is forget the engine "normal configuration" nonsense. Taxi should take care of it for you. When you are lined up on the runway,
stand on the brakes, set N1 to 70%, then when they both equalize, set release the brakes and set T/O power. If engines do not both equalize at the same N1 when you runup to 70%, abort the takeoff and return to the gate.
