Has anyone done any E89 Z4 23i 6AT ECU Engine & Transmission Tuning?

I am trying to explore if there are any original BMW ECU mapping files that could flash the engine HP from 201 to 215, as per normally offered by the 25i model.

Since this Z4 model is equipped with a 3-stage intake manifold already, the engine could definitely provide more power than is offered by the stock.

Also is there any ZF6 transmission ECU that could flash to quicker shifting?
