it depends on what you wanna do with the car. If you are going for an all motor setup then a piggy back would probably be the best way to go. It will be much cheaper and wont hinder inspection. An EMS is what you would want to do for a lightly to heavily boosted setup although they are very expensive and will NOT allow you to pass inspection. Unless ofcourse you have hookups
