Does the Coob OTS tune code out the secondary o2 sensor CELS errors?

So, can a tuner really permanently stop catalyst below threshold codes from reappearing?

In my tune secondary O2's are completely disabled, as well as sensors.

Not without a tuner deactivating them. Call Sam, he did it for me with the OTS tunes

I'm not exactly sure thats how it works. I THINK the only thing that gets disabled are the potential codes from the seconday O2's...

I have been running catless for last couple months and have never got a CEL from it yet. I just put the o2's back in like normal and it hasn't been an issue yet.
