2015 Ram/Cummins emissions recall

Last year I got codes for 'insufficient catalyst'. I had recently topped off the DEF tank with cheap stuff. I later pumped out the tank and refilled with Peak Blue DEF. I never had another code after that but received my recall notice this spring. Had mine done earlier this year and was told there was a minor configuration change to the SCR unit and they also removed one of the sensors.

I think my mileage might be a little better now but I don't have accurate logs to say for certain.
