Excessive regenerations

Your outlet NOx is high with it dosing but there should be a Outlet NOx Corrected parameter to note as well which should be within to 80%+ efficiency range if all is well in that system. Provided your ECM calibration has been updated recently if its running below that 80 percent range it would also have a NOx conversion code.

Thank you,
Calibration was recently updated.
There hasn't been any nox codes. I did pick up a new nox sensor and just installed it. Also going to change out egr gas pressure sensors and egr temp sensor.
Going to change charge air hoses while changing the rest of the clamps
