One argument I find extremely unconvincing in the Porsche world is that Porsche didn't originally do it, and that decision must somehow necessarily have been a technological judgment.

Wrongo.

Porsche, for reasons entirely unrelated to performance, was still using CIS on its flagship turbos through the 3.6 turbo, for just one example There is simply no question that a well-tuned EFI system would have been "better" for that car, even more so than it was "better" for its NA 911 cars at the time, which did have EFI. But Porsche was in economic trouble, and didn't want to spend the dough.

Twin-plugging is better, as well, for the reasons stated here. For high horsepower, modification apps, it is much better.
