had a look but i do'nt think these are giving your performance troubles . Rear O2 sensor is the second one (lambda) , which does'nt do anything to the ecu/cars' mixture ..

I think the O2 sensor reading is probably there because you're running a decat ?

You do not need to delete codes, actually, the remap will clear them out. Just looks like the decat is causing the 2nd O2 sensor to fail as Franx said.

Use latest version of Rstuner software, and when clearing codes make sure you just open the switch, do not run the car. To me it looks like you are doing this with the car running. otherwise all codes will be shown as memory and not present.

Also backup your ECU and upgrade to 6500*.rst, the use the map to suit. there are three of them, I better like the 5E*
