Do not have a baseline A/F. Will be adding a wideband soon. Just continue to set rich codes. I DO realize plugs are not a solution. Just curious "generally" speaking, not even Viper related, do people change plugs to a different setting in conjunction to adjusting timing and fuel. If not, what is the purpose of having hotter and colder plugs?
