Hi there,
I'm in a similar postion, again looking for upgrades to the 125 f20 lci.
Have a look at Evolve Technik
http://www.evolve-technik.com.au/
They are one of the few that operate locally, however are very pricey. They quoted me 1600 aud for a chip tune, however offer local benefits such as a drive before you buy policy, which is not as easy when ordering chip sets from Europe. However these are much more financially attractive. I myself am looking at racechips, however will probably wait a couple years for it.
