Depends how much you want to spend. Power fc if you already have one would be good and can get good results. Link is not cheap for quoted close to 2k and then it is only as good as the mapper anyway. I would most likely go Syvecs route and so far only person that inspires confidence is Ryan G - will probably cost me bit over 2k.
that sounds like good advice , I don't need launch control and have z32s so afm restriction isn't really a problem. It just seems that people are saying the fc is old tech but with limited funds I guess its still up there- just looking for advice either way.
Was tempted to go for the PFC because you see so many cheap second hand ones, but on reflection I think if you can budget one I'd go for a link, simply because it's new tech and has more options if you decide to change thing in the future.
