Well in all actuality, commanding an increase in ICP does have an indirect "advancing" property to it as well.
As far as lowering the entire MFD map......yes and no.
You can lower the values enough to give a dead pedal.
Another idea would be to lower the fuel limit for RPM map and set the low boost fuel map to give the desired result and still be drivable. It's a balancing act.
I'd just put an egg on the accelerator pedal.
