I guessing/presumeing that i would get away witha fmic on amy99wrx with out having a re-map

what i mean is do the aussie ecus runas rich as the uk ecus from factory?

but will i get away witha vf34 as well or am i asking for trouble??

if so can these ecu's be ecotek like the uk or will i have to for a verso/autronice route??
and how much would that cost??

just wanna find this out before i ring the guy with the blue wrx and make a offer as i think i will go with that now...
