the fcon sz pro i think it is, is pretty good, much like most of the hks ecu stuff but the problem is there are no local tuners, so you need to be in sydney and you only have like 1 or 2 tuners so they can charge you any price and give you any level of service they wish and you have no choice, you cant just walk away and go see someone else.
if there were lots of hks tuners in australia, sure go for it, but dont bother in australia, unless u have unlimited money, then if you do buy motec
