Why dont you start where Porsche designed the stock ignition and go a little bit forward from there?
You can get a hold of ignition curves off this site or the owners manual so you know the timing parameters and then just modify your starting points, meaning idle timing settings, to advance a little from where the factory set things. The factory set idle timing retarded to improve emissions and make the car run hotter at idle at the expense of power and low speed response.
This would give you a baseline to start from. Only way to optimize is like said above post on a dyno. This takes lots of money in tuning time....which is why alot of guys in the know dont offer up details.
