But getting a chip for our unique NZ/AU ECU's is a nightmere,

No, 93-95 Octane = 98RON

Octane and RON is not the same.

Octane= (Research Octane number + Motor Octane Number)/2

ie Octane=(RON+MON)/2

5 Bar Regulator.

You stock injectors on you model with K-04-15 are fine.

Spark Plug should not have to be changed if they are still good.
Some tuners insist to install colder plugs to prevent pinging, but if tune is correct it is not required.
