Cat protection on if you have cats and care about them.
Cat protection off if you don't have cats or don't care if you melt your cats.
If you don't have cats the car will stink regardless of tune.
If you don't have an EGT sensor installed and functioning you might as well disable cat protection as it's not going to do shit if it can't tell what temp the cats are
