AFR QUESTION

Quick question about "STOICHIOMETRIC AIR FUEL RATIO" in the bin file. I'm running a speed density TPI on a 305 El Camino. I know the stock AFR in the bin is set at 14.7. If I was wanting to run a little richer, could I just change that setting to something like 13.5, or will the narrow band O2 only adjust for 14.7? Also, if I can adjust that setting, will I need to retune my fueling tables to compensate? Thanks in advance for any help!
