O2 Sensor CEL

[REKIII]

I have a Tune on my 17 as well as downpipes with high flow cats. I keep getting the CEL for cat out of range.
Any tunes get rid of this? What are my options? Need to get it through emissions.
Thanks!

What down pipes are you running and what tune. I know you can add o2 extenders with SPD.
