I ordered the software today and will report back with subjective feedback in the next couple of weeks (doing the Glen on May 18-19 and Pocono Long on May 24). Objective dyno data will be later in the year.

Yes, it's already been done. I was the first on the forums to get the tune and there are several others that have also gotten the tune for their Z4Ms. Check out the thread I made for more info:

Okay so you got the tune. Do you have headers or other mods that the tune helped with gains?

Tune alone, I went from 266rwhp and 235rwtq stock baseline to 295rwhp and 243rwtq on the same dyno, different days, similar ambient temps.

There are plenty of others that have the same tune, but over the last two years or so, nobody has been able to do another "stock vs. tuned" dyno (provided that the ECU had enough time to fully adapt)

My highest yield was with additional bolt-ons at the time:
AA NA tune for 91 octane
RPi induction system (scoop + drop-in filter)
JVT headers
SS uncatted section1
SS x-pipe
SS race mufflers

And that put out 310rwhp and 256rwtq peaks; again, on the same dyno with similar ambient temps.

Edit: On a side note, I "extracted" the AA tune in lieu of flashing in a new tune for my VF570 SC kit about two months ago. I do miss the smoothness and overall driveability of the AA tune, but it's kind of an apples to oranges comparison since I now have much higher-flowing fuel injectors with this SC kit and the characteristics of fueling are drastically different from stock.

Edit2: Before I had VF look over my kit for any air leaks, etc. my kit put out 370rwhp and 300rwtq again on the same dyno.
It should now be around 450rwhp and 320rwtq.
RatedMRoadster's VF570 put down 472rwhp and 330rwtq on a DynoJet for reference.

When did you get your wheels? Light weight wheels could be worth around 10hp.

The dyno I have most access to is a DynaPack which connects directly to the hubs and foregoes wheel/tire combo, so it is out of the equation so to speak. In any case, I doubt wheel/tire shows up on dyno. It'll make a bit of difference in real-world application but I always discount stuff like that for consistency sake or treat them as neglibles.
But to answer your question, I've had these same wheels since like early 2011

Ah, in that case it has no bearing on your dyno numbers.

If you follow the link I posted you'll see that it does (on a traditional dyno, not a hub dyno). If you search around you'll see many similar tests showing a small increase (10hp or so) from lighter wheels, here's another example.

the reason i am checking tunes is yesterday I installed my new FAB Speed cat-less headers. After about 30 miles i got my CEL. I am wondering if the AA tune will fix the CEL?

The AA tune can get rid of CEL from headers, but depending on your state's emissions/smog laws and procedures, you may have trouble passing.
