Default Changing injector preassure to half. Anyone done it?

I have been a reading and I hear lower injector pressure = better MPG. So, with that theory in my head, I was looking for anyone that has gone to a 3xlb injector and dropped the pressure regulator down to 4xlbs or lower on a stock build?

Yea, I know, probably too many --> in my lifetime, but, what can I say?

No. Just no. That's not how this works.

Great question for the Fueling and Injection Section...not so much the Internal Sections.

Higher pressure atomizes the fuel better....within the limits of the injector being able to handle the pressure.....Then there is the whole tuning fiasco on a PCM that expects 4Bar.

I thought that also, but, while fumbling for other info I kept running past "lower pressures with the given same volume is better" and was like.........whaaaaaa??? I need to find the articles just to double check and maybe share.
