Or have they just not chosen to put a larger pulley on it and see? Sorry if this question has been answered previously, I don't think I have overlooked it in my reading through.

As I understood it, and please correct me if I'm wrong, 8psi is the top of the range of the efficiency zone of that unit. Higher boost applications would require moving out to the Stg2 compressor...

Eh, the cooling effect helps keep the mix from igniting prematurely, but power gains are negligible. Lot of people say untuned "X" injection actually loses power because it inevitably takes the place of some fuel that would otherwise be burned... anyhow..it will work to keep your motor a little safer...
