I would SO love this but after the constant popping of cat-conv codes in my previous car with high flows on it (even tuned for them), I don't think I want that again.
I'm thinking all late-model cars are strict enough in their emissions systems that they'd pop cat-converter inefficiency codes ...
What are the chances that THIS unit would do that?

And yes, the car was tuned for it but was still setting codes

I can't comment on the new car yet as I haven't gotten into the tune yet. But in my 98 if you let the sensors on in the tune it would throw a code. But as long as you turned them off you had no issues. I would imagine since same tuners with same abilities that they can do away with the codes. Don't know much about the computers on the Chargers though.
