Now heres the interesting part. I no longer have an oxidizing catalyst nor an operating EGR and the ALDA is turned up for maximum power.
Looks like the emissions crap only makes it emit more.
The oxidizing catalyst reduces Hc and CO emissions.

The EGR reduces Nox emissions.

The test is not related to any of these components.

You would have failed miserably if these items were tested, as if it were a gasser.
