w/ MHD (or any other tune) you can disable the CEL dash light for the cat deficiency code, but it will still fail emissions when I go in for testing in California (praying the code will magically disappear before testing). I'm able to clear the code with MHD / Protool, but after a 20 minute drive the code pops back up. I may experiment with a gallon of E85 or different gas station brands to see if that makes any difference, still have until Jan 2021 to mess around with it. Maintenance wise I want to say I'm up to date, but maybe I'm missing something.
