Am I interpreting this AE scan correctly?

So I have been toying around with this thing today after running trouble codes and a buzz test. I think number 7 buzzed at a little different tone but no to the point of any errors. My next adventure was to check my ICP/IPR and this is what I came up with...Let me preface by saying that I hit the pedal hard for WOT but did not floor it going up the hill so I hope that is good enough. If not then let me know.

At idle after warm my I got this
RPM 675
Injector control pressure 480
Injector control pressure duty cycle 10.16
ICPV .80

When I periodically hit the gas pretty hard going up an ok hill I got the rpms to just below 3000 (2976) with ICP at 2803 during that rpm and a duty cycle of 39.

From my novice interpretation this is good correct?
I was under the impression you did not want duty cycle over 65 under 1000 psi and I am only getting as high as 40 around 3000.
If good does it essentially "suggest" that my injector pressure/orings and HPOP are up to snuff at this time? Anything else that it suggests.

Bonus question...What would you test next?

Both your icp and IPR at wot are low. Icp volts should be around 4.5-4.7 and IPR should be 84%, when the IPR is at 84% it is commanding all the high pressure oil available (which is what you want at wot). Maybe you IPR screen is getting plugged.

Edit: at idle icp should be .8-.82 volts (480-500 psi) and IPR should be 20-24% at an idle (while hot). So I think your icp number is okay and IPR number is extremely low when idling.

Just realized your engine is a 7.3 and I'm not 100% sure what icp IPR number should be on those engines. It's my fault by not paying attention to what section this was posted under but it helps to have your year of truck in the original post or better yet a little info of your truck in your signature. Good luck!
