I had a tune done on my N/A some time ago and already have the cable. From reading the posts I'd be getting updated software free via email that I could use at my leisure. Is there an expiration date that will be assigned to the new software or am I reading something else into it?

Now that I'm also an SRT6 owner I'm guessing that I'll need a separate software package to tune it. Does the same time parameter (if any) apply to a new software package? If not, put me down for 1 on the SRT6 list.

On a side note, does this new software work on the Mac? I may need to suck it up and downgrade to PC instead of borrowing one.
