throw the hyper sfc in the bin, no one in australia will be able to tune it and get it right
either buy;
remap your stock ecu (limite local tuners)
safc (should be tons of local tuners)
greddy emanage (make sure you can find a local tuner first)
stand alone ecu (motec, autronic, powerfc, wolf 3d,) - ask some guys in your area what they tune
