CC25: You don't need bigger fuel injectors

It's a rather common misconception that intakes, intake manifolds, throttle bodies and other intake parts add more air to the engine and therefore bigger fuel injectors are needed to take advantage of that air.
Well, that's false. Not only do these parts not cause a higher fuel demand, in any situation the computer mostly sorts out how much fuel goes into the engine. Adding bigger injectors can confuse the computer's function and mostly you'll be running worse.

The injector duty cycle is also another good indicator if bigger fuel injectors are needed. The tuners I’ve worked with recommends bigger injectors if duty cycle is > 90%.
