    Any DTCs to change to NER for/during MAF tuning?

    I?m trying to put together a list of settings I must change for my attempt to tune my MAF on my Silverado. I?ve found a wealth of info about tuning the MAF on this forum and on YouTube and I think I?m going to be able to pull it off. I?m not able to find any info as to whether or not I should set O2 related DTCs to No Error Reported or is it okay to leave them all as is while testing. I?m not removing them physically but I?m removing their input via the tune I will use for tuning the MAF. Any info greatly appreciated!

    Shouldn't have to set any o2 sensor code to no error reported for MAF tuning of VVE tuning.
    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.
