Ford states that for their ecoboost engine the fuel rail pressures vary from 200 to 2150 psi depending on the demands of the driver...

It is true what you say about increased atomization which is required for faster vaporization which is accomplished by an increased number of smaller diameter holes on the injector.
I guess the need for higher pressures would only come from multiple injection events, which take place at different times during the compression/combustion cycles. That paired up with changing combustion timing. Maybe I'm diggin too deep lol...

Btw...didnt mean to thread jack.
