Just a thought, twin plugging may have a different function on a Turbo than a high compression NA motor.

It helps fire the AF mix with low compression pre boost. On boost the mix is so volatile we only need one plug. Note the 993 TT and the RUF Yellow Bird. Per the factory twin plug on there race turbos the second plug was as much insurance that there would not be a miss fire. I could be wrong but that is what I believe at this point in my learning curve.
