Need help with EGR quick

One question I do have is is it ok to just shut off the AIR and EGR codes in the computer(delete them so the computer doesnt even know they are there)? Or do you need to do that and get a tune? If the check engine light is off it shouldnt go into the "closed loop"(rich tune) should it?
