Double check with Bama To make sure they turned off the sensors. You should have the tuner so you can check it yourself and change if necessary.
Are you sure the code is for the rear o2 sensors? I got a code for my fronts and it turned out to be the Bassani X causing the issue. I switched to a UPR o/r X and it solved my issue.
I still have the tuner, but there isn't an o2 option to turn off. I'm pretty sure that it's only written into the tune right? And not opening up the option for you to turn them off .
So I called Bama, and since I am getting code PO430, that it's the passenger side o2 sensor failing, and that I don't need the eliminators. Why is the computer still reading a sensor failing if they are turned off in a tune ?
It might be faulty MIL eliminators. I had a off-road mid-pipe on my old GT and was throwing a code for catalyst inefficiency and when I put the MILs on that code went away and a code for a bad O2 sensor came up. I took the MILs off and the code for a bad O2 sensor went away and the catalyst inefficiency code came back.
