Ok, seeing as im kinda new to the TDI's, ive spent most of my time playing the IDI"S, what would be my best tuning options as far as programming and such goes for the TDI's, with the one in question being an "04 golf, I know bully dog has one, but it is only a plug and play unit, what im wondering is, if there is somthing like EFI live for these cars, which would allow you to change the settings in real time.
