2015 prostar isx15 cm2350 fault code 2754

[Jrb8816]

im having a reoccurring issue with fault code 2754 on a 2015 international prostar with a cummins isx15 cm2350. i have followed all of the trouble shooting for this fault code lined out on quickserve. several intake and exhaust leaks have been corrected. the dpf was sent out and cleaned. the doc had to be replaced. i reset everything dpf replated using insite after reinstalling. the only thing in the trouble shooting that still doesnt pass is the regen analyzer. it fails for "engine percent load above max specification". quick serve instructs me to run a fuel injector performance test. it passes this test. retested to be sure. quick serve says that the fueling adaptation coefficients need reset if the test passes. i followed the procedure on quick serve and it seems to be just a fuel injector reset. i removed injectors and inspected. everything appears to be good. i reset the injectors after reinstalling. the truck will do fine for part of the day then fault code 2754 comes back. the regen analyzer still fails for the same thing and during a regen the percent load bounces between 3 or 5 % and then maxes out at 100% staying at 100 most of the time during the regen. any help would be appreciated. sorry if i asked this question in the wrong place. im new here.
