hey wus sup everyone. someone was selling a ctr ecu and i was wondering if i should get it. my homeboy told me to get a better ecu so i was wondering if i should get the ctr ecu. if not then what ecu should i get. and how much horsepower will it give me. i have a 99 civic si by the way.

 

I recommend you leave the car the way it is. You have a lot of learning to do before you start making changes like that to your car.
