Flashing is the way to go i think if your around someone who does it. you dont really need a tune but its nice to have.
If you want to keep it simple for yourself, buy a powercommander. Otherwise you'll need a laptop, interface and software to flash the ECU. Flashing provides greater scope for tuning and removing restrictions and better bang for buck.
Since you are in Victoria I think Biker Boy (Paul) has an interface and probably could help you as he is really good bloke. Send him a PM and ask. However I think you still need the tune-up to get the best of your equipment (including the exhaust) as I doubt whether someone will will have exact maps for it, plus each bike is a bit of an individual.
Still flashing will help as you can change some settings and remove the restrictions

Mate the ECU Reflash is dead easy and you won't need all that gear. I sent mine off in an Express Post bag to Pete's Pitstop up near Gympie (Qld). Google and then just give him a call. Great bloke. Tell him a bit about your bike ie. type of exhaust, air filter, fuel type etc. He has done hundreds of tunes and dynos on hundreds of different bikes and setups and he will no doubt have the perfect one for you. Cost is about $285 plus postage to and from. You just plug it back in when you get it and the difference is amazing. Just give him a call and have a chat about it. He can answer any of your questions.
I may have to call Pete as well for some advice regarding my SDS tool... it won't connect to my bike, whether it is a software issue or not, Im not quite sure... I've had to uninstall and reinstall the software several times, but keeps freezing... and help or advice would be appreciated..
