Under Engine>General>O2 Sensors>Rear Config: Change to None.

Under Engine>General>O2 Sensors>FAOSC: choose disable.

Under Engine>General>)O2 Sensors>02 Heaters>Heaters: Under Column Axis S2, change values from 1 to 0 in both Bank 1 and Bank 2. You probably don't have to modify the last two parameters, but I always do just to be safe.

^^ that right there, I turned my heaters off too just to be safe. My rear o2's are 100% deleted, not just in the tune but physically deleted, unplugged them never p ut them back on since since my new X pipe doesn't have bungs for them anyway. I think you also need to disable the catalyst test. Just know that everything you are doing is intended for off road purposes not to be driven on highways...etc etc etc

you can leave them enabled if you wish but assuming you have no cats I would disable them so they do not affect your fueling
