Speaking from experience with the AP on my Speed3.... it doesn't let the readiness codes set. It masks the CEL but when they check at the emissions place it will say not ready and they will say "Did you disconnect your battery recently? You probably just need to complete your drive cycle."

Example:

I had the EGR removed and cat... EGR and cat both still said "not ready" after a full tune on the AP. You are allowed 1 not ready though.
