I have GMC Yukon XL Denali 6.2 AWD 2011. Catalyst system cutted off. This is my tuned file and i have some concerns about flags and DTC errors, can someone advice which one can be switched off?

And this one stock file.
You turned off all the O2 codes. You should turn back on all the sensor 1 codes. (pre cat O2s) And there is no reason to disable the system rich and lean codes.
Ok thanks a lot, it was as well my doubts as well as it was advice from one of the tuners.
