Perhaps reach out to Openflash and ask them to confirm the tune you are using is for the header you have mounted. Also ensure that you have no exhaust leaks at the header flange mounted to the block. Clear the code, Mount the tablet, monitor AFR when you're driving so you can see what is actually going on the next time that it comes on.

I've not had to deal with this code but I am running an OFT Catless UEL header and OFT, off the shelf tune.
