If you like having a warranty, you might want to flash it back. Although they can probably tell.

Re-flash back to stock. Disconnect your battery overnight to clear all the memory.
Drive it and try to duplicate the cel and bring the car in for diagnosis.
Good luck.

how long has the tune been installed?
do you have the stock air filters and the carbon filters?
when did the codes appear, ie, after the tune or filters?
the codes seem related to a lean mixture
don't the tunes lean the mixture to get some power?

put the stock map in, clear the codes, and drive the car and see if they return
