The CEL delete should get rid of the code for you. If you have to pass emissions, the CEL delete nor the tune won't pass emissions for you. The tune will auto clear the DP code so you won't see the CEL on your dash. However, if sometime does happen with your sensor or emissions and it actually throws that code, you won't know it because it auto clears it.
What some people do is install a cat simulator that tricks the ECU to thinking that the cat is running normally and put the cat into ready state, allowing you to pass emissions. This won't throw any codes and if your car actually throws the code, that means something is wrong with your emissions.
