On my 83, it depends on the elevation. Here around Denver, approx 5000 feet,
I can run around 13.5 - 14psi boost with the stock computer, depending on
the air temp. When I took my car to Minnesota, it cut out instantly once I
jumped on the boost. I ended up turning it down to around 10 -11psi boost
and I could accelerate at full throttle at this setting.

There is a curve in the "quattro : introductory service training
information" manual which shows this. I can't remember the values and don't
have the manual handy.
I have never heard of a problem with the distributor cap like that. Sorry no
