Dkruid 410

Any help would be appreciated. I currently have a 2003 410 Sundancer that I purchased about 3 months ago. I am having a problem reaching the proper rpm on the 3126 TA diesel motors. My WOT is 2500 RPM and all the spec I have read and the CAT mechanic says it should be at 2800 at WOT. The CAT guys say everything on the motors are perfect but his concern is that the boost from the turbo is not going down once the boat reaches WOT and gets on plane. I have swithced the props with new ones I got with the boat which are the same that I took off 22X24 Nibral 4 blade. Another 410 owner stated that he is going to 22X22 and that this helped his RPM reach the 2800. My concern is also the speed of the boat. All test I have found have shown 32-34 MPH with full fuel water and 3 people on board. My old props have been sent to a prop shop and they say they are going to make them 21.75 X 21.75. Am I going to far with them and will I lose all of my top end speed. Right know with the motors only getting 2500 RPM I am running about 28 MPH.
