I understand this is a NA car, but are there any tunes? And, if any, the best bang for my buck? I'm very familiar with FI tunes on my M4 and S5 so this is new territory for me. I'm definitely going to do the muffler/resonator delete - any other low hanging gains/sound improvements to be had?
Thanks...

 

RR racing mid range tune is the only one available to the RC-F. This is nothing crazy like M4 and S5 tunes. I think they are still working on a real tune with a supercharger.

 

Rafi w/ RR Racing can do the RCF. most people do full bolt ons which include headers, intake and exhaust.
RR Racing also just announced the Supercharger for the RCF which they announced a few months back for the ISF. 165 whp gains over stock

 

I wonder how the RCF with just a tune will do against m4?
