GoPower is out of business now.
I can vouch for perkyperformance, also the only tuner i would recommend for the R18 he knows what he's doing as he owns one personally and has personally designed all the cams.
Josh knows his ish go to him to get your cam let him know you're also looking for a tune and he'll probably hook it up guys a beast and really doesnt stop tuning and tweaking till its done. He owns and built an R18 of his own hes definitely One of, if not the BEST R18A1 Tuner in the US.
hondata hasn't even started for the r18....I have a buddy that works for groups a auto sports which owns skunk 2 and kraft werks supercharger. He just told me they are designing a supercharger kit for the 2012 2013 non si civic. So I imagine there must be a flash pro being available real soon.
thinking about getting cams for yours?I just shot another message to Perky Tuning about their R18 cams they have been working on. Haven't heard anything back yet but it's a small operation and just a couple days before christmas... Ill let you guys know when I hear back from them. The guy who runs the place is also a very good R18 tuner from what ive heard and read from other boosted non-si owners.
