Thanks.. I have A PCV with its 02 optimiser on my R. Currently it has a generic map on it which tbh isnt that much different to how it rides with both Kev's mods on it.
I have stage 1+2 DNA air filters,air box drilled(as per Kev's mod) and Arrow exhausts.
Im in process of finding a localish tuner to puy it on a dyno..fingers crossed.
