So the issue was not with the AA tune after all (at least it did not appear to be).
I had verified that I competed the drive cycle numerous times to set the readiness monitors (

I had cleared the previous catalyst codes after flashing the DME. I had not reset the adaptions. As a member on here had pointed out, that was worth a try.
Resetting the adaptions ended up setting the o2 readiness but not the catalyst monitors (which likely would never set without the presence of cats). I had never thought to do this as I was under the assumption that adaptions are related to engine performance/optimization, not emissions readiness and monitoring.
Anyway, 1 monitor in the “incomplete” state is allowed for cars to pass emissions in my state. So resetting the adaptions had saved me from selling my car lol.
