    05 gto o2 sensor help

    I have a 05 gto m6. Stock tune on it, looking at my dtcs to shut off rear o2s, noticed the bank 1 and 2 sensor 1 are off, I compared my file to other stock files and they are the same.
    Why are they shut off ?
    Should I turn them on ?
    Thanks in advance.

    Post the tune, they are several o2 codes per sensor and per bank.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    sorry I got back so late, I workover night.

    in the tune I shut off cags, took off torque management, made fans kick on earlier and shut off rear 02s.
