More boost = more power and more power = more fuel and more air.
Too much fuel and not enough air means black smoke from the exhaust (safer option). Too much air and not enough fuel means engine detonation (unsafe). Less amount of fuel (to the point just before being unsafe) with the right amount of air and timing = optimum performance. The factory releases them with the safer specification (running richer) so it doesnt matter what conditions you put the car under, the engine wont detinate. Yes if I put my foot down I will consume more fuel, but day to day driving, I will save fuel. When I first got my car before any mods, I would get about 530-580km out of a tank.. Now I get 600-650km._
