Hey. I have a BF2 xr6 non turbo 1 ton ute that I have flash tuned. Its an SCT X3 with 3 progammed tunes plus you can tune it yourself all for $800, or buy one from the US for around $400 and write your own tune. Plugs into the OBD2 port. You can go back to factory tune with a touch of a button if it goes funny too. Supposed to give 10 - 15 kw extra, I havnt had it dyno'd but im sure it would be more than 10 kw increase running on 98 octane, other people have noticed this( not just me) and I have picked up between 30 - 50 km extra range to a tank of fuel. I am satisfied with it and recommend it.
