The prop is adjustable, it is hydraulically controlled.  I current have it set to the fine pitch setting.

If it's adjustable you may need more pitch. A 2150 rpm limit seem very low.    Bobby

Perhaps the throttle is not opening all the way?  You would have to have a pretty convoluted intake to lose 3" of pressure in it.

My static MAP before starting the engine was 23.3
