Repost, AFR please

Can a few people Put down there AFR at:

Idle on cold start:
Idle warm:

~2k rpm:
~3k rpm:
~4k rpm:

And full throttle:

I'm trying to figure out if my tune somehow went bad, my AFR guage is toast, AFR or sensor bad, or my upstream o2 sensor is bad. My car is running lean. She fluctuates in idle anywhere from 15-17. She starts and drive fine. I have not put her in boost past 2psi yet. I also thought I had knock on start up but I don't think I do. I did an oil change and don't hear anything under the hood. AFR still poop though. What do you guys think is the problem?

I had a code saying my passenger upstream O2 was bad again. I just replaced it within a year ago. Car is down and out until I figure this out.
