How much of an improvement performance or horsepower wise does an ecu computer computer and fuel management system supply. I just purchased this civic and im seek suggestions on how to build this car up to make it alot faster.

 

Why upgrade fuel management if you have nothing aftermarket to manage, same for the chip. Slow down man, you have a lot of work to get to the point where you start screwing with that stuff. Search around, youll find all the basics, and then steps to take it to the next level.
