Help with fuel pressure

[Piluso1]

I need help with a set up for an eta engine. I have a Turner chip, Bavauto raising rate fuel regulator and a k&n filter, I'm running stock idle fuel pressure, but it keeps running rich and burning the o2 sensor, any ideas? I don't wan't to go to bigger injectors due to that problem. But I couldn't figure out a solution.....

You may need to adjust the AFM. I couldn't tell you how to do that but the mechanic adjusted the AFM idle mixture on car while monitoring the O2 sensor when doing the emissions test. It was clearly able to change how fuel mixture that way.

I don't know if rich running would burn the O2 sensor though. The catalytic converter definitely but I don't know about the O2 sensor.
