Yes, it would.. but the strange thing about it is that the amount of fuel added decreases as load increases. When the engine isn't under load, it can run very lean.. I run at 15:1+ under light load in my mustang, but don't like to see less than 13's under heavy load. It shouldn't need that much fuel at idle.
