since everyone thinks that you tune a car for nitrous let me enlighten you on something. you tune a nitrous kit for a car. if you dont wanna pull timing out because you cant afford to tune a car you put a wet kit on the car. then you put the right size pill for the shot of nitrous you want. then as far as the fuel you put a bigger pill in there to add more fuel so the car doesnt deadnate. everyone knows if you have enough fuel you dont have to pull timing out of a car.
