Regarding ignition, I believe it depends on what type of engine, effectively your distributor, and what fuel grade you run.
Do some more research in this, but I think (from memory) somewhere between 26-29 degrees is safe.

Once you got your idle and ign sorted, it is time to tune the WUR. This involves either getting it modified or buy an adj. unit.

Fourth edit :
While this is not Porsche specific, it gives a good understanding of the importance of tuning your engine properly:
