The mix of air to fuel, or air-fuel ratio, determines how much energy is released and how much emissions are produced. Carmakers tune for the ideal air-fuel ratio, which is 14.7 parts of air to one part fuel. But here’s the thing. That ratio might be ideal for maximum economy and emissions, which is what carmakers want. But it isn’t ideal for maximum power, which is closer to 12 to 1. This means your car is capable of more power. And that’s where tuning comes in. The challenge is that cars have gotten a lot more complicated and so has tuning. When engines first a
