New Pump or Sensor?

Hey all,

I have noticed a decrease in power lately in my car. I have an upgraded (stage 2 LPFP) that I have been using for about 2 years and it has begun to dip into lower psi. The only code I have been getting is 2AAF. I have been told to ignore it if it pops up alone, but the car has been feeling sluggish. I have my logs below. My question is, do I need to replace my LPFP, or is it just the fuel pump sensor?

I asked my tuner, but he has not gotten back to me.

Did you upgrade to the updated LPFS?

This is the updated version.

If your version is brass, it's the old one.
