I don't think there is a lot to be gained for our Aust model in a chip change. Our model doesn't have the severe polution maping that the US model has, all we really need is 98/100 octaine fuel, to allow the ECU to use the full potential of it's maping. The lower fuel has the spark timing pulled back a bit.
I heard that the fuel Co. are raising the octaine of our fuels from 92/96 to 96/98. this will bring it inline with the Japanese fuel, so that their imports won't have to be retuned for our market.
