I really don't think that is a good plug for Porsche.
use copper plugs.
bosch supers or NGK.
those you cant gap.
if it pops at steady RPM you are lean/ have air leak.
if under acceleration it is the vacuum portion of the WUR. the CP drops under acceleration.
been quite a while but when I tested mine with the vacuum removed it popped and sputtered under accel, but drove fine at steady speed

I really hope the bold statement is true. Ill check my timing. Check TTV. Search for further air leaks. Try different plugs. Check mixture again. In that order. #fingerscrossed
