hi all,
After some info on the best way to approach this.
I currently have an safc2 fitted to a series 1 r33 gtst it has full turbo back 3 inch with hi flow magnaflow metal cat standard turbo apexi pod and ebc set at 10 psi, r34 smic. Currently sitting at 171 rwkw tuned by mercury in bris.
I have been finally able to obtain a apexi sitc, (rare as rocking horse shit), question is once it is installed will i require a full retune or is it a matter of mechanics having a fair idea of settings, also what do i need to explain to the tuner that i want to sacrifice top end power to give it more low end pull (rarely rev it over 6000 rpm).
Thanks
