Hey i got a 2012 civic si, i’m planning to go full bolt on in the future with a down pipe, cai, performance fuel injector and possibly new headers to pair along with my performance park plugs, and full catback exhaust. I’m just trying to get people opinions on types of tuning. To my knowledge there are the two most popular flash tunes, the ktuner and hondata. but with both i’d have to do everything myself (which i don’t mind) but i’m honestly scared to **** up especially once i put all this money into my car. Is it worth the trouble to learn flash tuning it, or best to get a custom tune from someone with a dyno. Pricing is always an issue but depending on what’s more worth it i’d don’t mind either.
