Spektrum Setting head speed

Hi all, Another silly question. I fly my heli without govenor just on a 90% across the board setting. What I have noticed is the head speed changes when
I go from IU1 to IU2 when in fact all the settings are the same. I can not work out why the heads speed should change. It runs slower in IU2 when
all the settings in the TX are the same at 90%. Normal flight is also set at 90% across the curve. I'm sure there must be a simple answer to this and I am missing something. Any Ideas
most welcome. Thanks.
