Let me run something by you all...
Now,I doubt the likes of Star performance have umpteen software experts on their books,so they are either buying the 'tune-up' software from someone else or it's already there 'lurking' in the OBD.
Now,you may or may not also recall that an ex Audi mechanic I know,who still services and repairs cars for chums,plans to buy some VAG hardware and software to access the OBD....
Can you see where I'm going with this ?
I'm not trying to deny the likes of Starperformance a living but,at the same time,I don't see why I should pay,say,£500 for software that they have bought for far less themselves.
Just a thought !
