High negative af learnig 1a-c values and weird temp issue

[subiesin1]

Hey guys what would high negative af learning 1a-c be an indicator of. I have a vf52, grimspeed tmic, aem fuel pump, and a turbo back. For a while the car has been feeling a bit for sluggish then normal. However when driving today it started misfiring whenever going into boost, erratic and falling right on its face. When not in boost it revved up fine. No check engine light and after 45 mins of driving home staying out of boost I did a pull and things were back to normal except for the high negative af values. I didn’t touch or change anything except for breaks I did that day.

 

Second thing, weird temp issue. My temp gauge is never at half, it’s always below but not just slightly sometimes it’s more like 1/5 away from the half way point, and I’ll see it foucate back to the normal half way point. Thermostat has been changed and every 4 months or so my car will ranndomaly overheat, never let it get into the red but it’s gotten to the line right before it a few times before I pull over.
