Sorry, I just ran into this thread randomly. I'm not a Z4 owner, but a 328i turbo owner. But I think the value of this thread is being diminished by all the arguing. I think this is a really good idea. This could be applied to the 335i -> 335is tuning as well
I can imagine a lot of people would want the 35is map as it was R&D'd through BMW. Some people don't get tunes because they think a custom tune is bad for their car or will wear out the turbos faster. This worry is completely put at bay by using a stock 35is map.
