No... "overkill" is doing something like sticking a 727 behind a normally-aspirated slant six. A half-inch fuel line will do nothing to reduce performance. Who knows; someday he may decide to build a really fast runner out of this thing and apply the forced induction magic to it, and he'll already have most of his fuel system assembled in a way that is compatable with a boosted motor. For now, though I agree, it's not going to do anything for his performance, one way or another...
