PO138 code

[MS3Edge]

Ok i have searched and haven't really found an answer to this. i have started getting the code PO138. it only happened since i pulled the stock DP out and replaced it with the Corksport catted DP. SO 2 questions (And i am getting nervous about posting questions these days) 1) if anyone knows what this issue is relating to. what i have read it 3 possible things either to much fuel, bad O2, and one other but can't remember. Now the car is a 2013 so i think it could be a fuel issue maybe to much like running rich and maybe when i get it tuned this issue will go away. the second question is this something i can live with as it seems to be ok once i have the car warmed up i can clear the codes and it doesnt come back. just looking to see if any other speed guys have run into the same issue.
