That is the reason for higher fuel pressures being used. Better emissions is the main reason. Very small power increase are simply a bonus.
I use injectors from FAST in mine.

I am irritated! I believe what your are saying. It makes sense. But Holley and Fast and some others say it's best to run fuel pressure at what the injector is rated at. On most injectors they are rated at 44.5 so I've got mine right at 45. I will raise the pressure next weekend.
