You can by it from Vcm Suite Australia, they have a on line store and are located in victoria. About $900 buys the Pro version with 8 credits. You are better to load the stock tune and save it as the base file and then reload the sct tunes and save the files and use the compare function of the software if you want to veiw the differences.And yes you can buy with your mates and tune a couple cars with the credits supplied. Two credits per Ford vehicle and the software updates are free. cheers Some Tuners Tunerlock but afaik this function only works on GM tunes.
