I've scanned the postings and don't see it that twin plugging is generally accepted to allow one additional point of C.R.
This applies N.A. or TURBO, once boost is adjusted, so there is potential HP improvement IF you take it. I've read that all Porsches will run smoother and was considered to be good for 10% on the smaller motors. Those of us who fly can witness the impact of twin plugs on vs single and it's the same issue as offset plug(s) and flame front movement.
I think with todays fuels, and 930s not having knock sensors, it's best taken as an insurance policy than HP.
