You really want to spend almost 3k for maybe 60whp? Also, IDK what downgrade means when it says fuel management but that looks to be a map clamp. That isn't a tuning device, you need to have it tuned after you bolt this kit on. It also says it is a 6psi wastegate on that turbo, weird that it would need a map clamp unless the newer civics can't read up to 11ish psi like the older ones.
