Stoich is 14.7:1 for gasoline engines. You cannot "set" stoich, it is a standard ratio for perfect combustion. But if you run an engine at stoich it won't last long as it will run too hot, therefore the "safe ideal" ratio is considered to be 13.7:1 and lean/rich is referenced to this. Hence yer maun's dyno printout reading that way.
