I think you have a wrong idea how air - fuel - spark mixture works in regards to power.

More fuel is not equal to more power unless you have more air coming. That's why on forced induction you need more fuel since the turbo is pushing more air into the engine. The same theory applies to more fuel needs less spark to detonate that's why cold plugs are used.
