Bill,

I do have the B&B system, so I agree that it is more of a design issue, coupled with the fact that the intercooler can see boost spikes, I think the best solution is to move the overboost sensor.

As to the protection against overboost, the records are pretty spotty and non existent on my car, but when I got it, it was running 1.1 bar worth of springs like I mentioned and the overboost was grounded out. It was running extremely rich, even more so since it hadn't been tuned at elevation (a little over 5000 feet here), I think to compensate for the massive amounts of boost. It has also been twin plugged and is running an electromotive crank fire ignition. Like I said, the info on the car was pretty vague, and my mechanic, working with Stephen K. (Porschedoc) set the cis, and tuned it with the .8 bar spring in.

On a side note, we did take it for a spin with the 1,1 bar worth of springs and WOW....

Hope that helps.
