Hi all, in dire need of assistance. Ive just installed the stage 3 manifold on my 06 3.0 z4, and was reading up on bimmerlabs faq page about installing the si tune, but then ran into a problem. The standard tools/ Sp Daten (whatever that is) is no longer available for download from bimmergeeks. Im not sure where else I can get whatever tools I need to install this tune, nor would I even know the process. Perhaps someone who has done this previously could give me a detailed answer. I am on a MAC by the way, however I could use a PC if totally necessary. Cheers
