If it's a tuning problem you will see the fca amps go to a set amount as the actual rail pressure continues to fall.

Posting a pic of the graphs like you did above including the fca amps would be best.

Gotcha, ill try that this weekend. Looking in my logger my options are:

FCA DC Actual
FCA DC Desired
FCA Current
FCA Volts
