Rear 02's still throwing an SES after tune. I just had my 2006 Tahoe tuned after a 5.7 LS1 swap, heads, cam, headers, full bolt on's. The problem I am having and after searching it seems to be common, but without a resolution I can find is... The rear 02's are coming back after being deleted in the tune. P2A04 and P2A01 both come back. Does anyone know what all needs to be deleted to stop them from coming back?

Depends on what tuner software was used. For HPT, you have to set the code to 3 - No Error Reported. That will disable the code from ever showing up.
If you just delete codes from the PCM's memory then they will just come back when the PCM once again sees the code.
No idea how it works in EFI live

those two codes are not ones that are commonly disabled in a tune when disabling the rear O2 codes...
whomever did the tune to disable the rear O2 codes, most likely didn't get those two...
