P015B - O2 Sensor Delayed Response after Headers

I keep getting P015B and a MIL after installing headers and tuning. Its bank 1 sensor 1 O2 sensor delayed response. Have any of you guys gotten this? If so, how have you dealt with it?

I don't have any drivability issues and no other codes. I haven't ruled out the O2 sensor being damaged during the header install. I thought I would ask here before dropping $100 on a new one if nothing is wrong with it. There's also the possibility that my old man put too much anti-seize on it during the install (few beers in at that point and wasn't watching him super close). I'm pretty sure I don't have an exhaust leak as I have inspected and retorqued everything twice since installation.

As far as tuning, I have messed with the airflow integrator delay and proportional band, but that hasn't helped at all. I'm pretty close to just disabling the code and calling it a day.

After typing this up, I realized I could swap bank 1 and 2 sensors and see if the error moves with it and confirm or rule out bad O2 sensor, so that will be my next step.

Thanks in advance for any help!
