Too much thrust require to taxi ?

[cmbaviator]

Hello,

I don't know if there is something wrong with ground friction but is it normal on a 2000 with a center tank, 2 530 and 2 Magic II, you need 70% N1 to accelerate and 65% to maintain taxi speed, the idle N1 being 48%?

 

It seems to be the case in almost every module though so its an ED issue ?
