Do you have pics of the original relocation when you had codes?

I have been running with relocated O2s and EGT and Euro M3 headers for about 2.5 yrs and no codes or drivability issues.

Others have had issues related to how the reloc bungs were installed - position or to long a bung that puts O2s far away to get a good reading.

Even with the post cat O2s out of the car, I just had codes but drivability was fine.

My details are here-
