AEM EMS is so overkill for your car, especially bolt-ons only, and not serious power making. It is best for high horsepower, and FI applications. I don't know if you can run chipped P28 or not. If not, you could always get a cheap used VAFC, or Emanage. They are good enough for you. Another thing, you don't need to get new fuel rail, stock one is good enough. Fuel pressure regulator is nice but not required, optional. Fuel pump is also good enough. I think stock injectors are fine also.
