Hmmm,
Assumed the tuner would have know that if it was rear 02 connected flex kit :-)
If they fitted a flex kit using the rear 02 sensor as input then the tuner needs to disable the rear 02 associated DTC in tune and also disable the rear 02 afr corrections.
I can understand the tuner overlooking a DTC disable but once you queried them on the CEL code/DTC they should have immediately tweaked to the problem if they fitted flex kit and/or tuned car with kit fitted
Simply clearing the code with a code scanner wont fix problem, needs to be done in tune.
