Welll... my dealer works with CTH chiptuning,
but since now they claim it is detectable by BMW,
they make you sign a form first that voids your warranty
So there's no advantage in taking their tuner.

And when looking for a good tuner, these are the most important things:

1-DYNO - if they don't dyno your car before and after, they're doing a lousy job
2-reputation - try finding other customers, see how satisfied they are
3-warranty - a good tuner takes over the engine warranty.

I only know the ones in belgium, so you'll have to look around a bit
