With "deletion" Fe dropped from 89 to 35, Al from 15 to 11, Pb from 2 to 2 bottle of Redline Breakin Additive to increase Zn and Ca 600ppm (from 840 and 1793 respectively). Also thinking about 15k OCI.
That SCR is ridiculously unreliable.
I just changed SCR cat with both NOx sensors. However, here we have emission testing so no delate.
Did you do new transmission adaptations or just left the way it is?
