Hondata

I have a 2017 CTR with bolt-on's, PRL flex fuel kit and the Hondata Fuel System upgrade. Started on the Hondata base map for 93 octane making sure timing was safe and fuel trims were within +/- 3%. Switched to E60 and started working with boost and timing. After a few pulls and adjustments, it made 393whp and 418lbs-tq but I notice that there was a dropped off after 6000rpm. I checked the logs for the throttle plate and that stayed 100% all the way. I checked for knock retard but no timing was pulled either. I started looking at the logs and notice that the Fuel Pump duty would increase and there was some major deviation between DIFP and DIFPCOM after 6000rpm. I did 3 test pulls the first time, and all show same thing after 6000rpm. The second time I lowered the AirC overall and especially after 6000rpm to see if that will change anything but notice that there is still some deviation between DIFP and DIFPCOM. Is that normal for the DIFP to drop after 6000rpm? Attached are the 2 files before and after AIrC change along with the corresponding logs. Any input would be greatly appreciated, thanks.

nothing alarming to me.

options are to reduce your fuel demand if the pressure deviation concerns you. Here are a few below...
a. lean mixture
b. lower airC limit
c. reduce ethanol content

I also suggest maybe playing around with the target pressure. You may find for your setup you might not need 200bar to achieve your goal. Key word "maybe". You will have to test on a chassis dyno to figure this out.
