talkpower flex 3000

Why is it that there is simply not enough talkpower in the flex 3000 radio.
I have setup my modulation several times using the audio gain distribution from W1AEX but my modulation is still much to weak

Only if i put the tx meter to mic en than put the mic slider up to 0DB at the tx meter, the modulation gets louder and better.
In this case the leveler and IQ meter is far in the red zone witch should result in a very bad modulation but the modulation sounds just fine!
This should not be the case of course so if anyone can tell me what to do to get correct settings and modulation would be great!!

I am using a flex 3000 and a Heil PR-781 mic.
IQ settings are at 0 db for the preamp with the 3 bands IQ
