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

This is not full throttle, I have to stop at 6000 RPMs do to the 2150 RPM limit on my prop. I am using a VARI PROP, it is great so far.   I have plenty of throttle, just prop limited.

23.3 is just about exactly what would be expected.

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.

At what density altitude was that measured? Maybe your MAP needs to be calibrated.
