because the way they add extra fuel is by raising fuel pressure. This is bad because your stock fuel system is not made to handle high pressures. Injectors will get saturated(stuck open) if you run them at too high of a pressure. The reason it is better to get a piggy back/standalone is so you can run bigger injectors that can be opened up for a longer period of time giving you more fuel without the high pressures.
