Get a good fuel pump that can handle high pressures and then run your base fuel pressure at 60psi. That will make 60's act like 80's and 80's act like 100's.
Yes the art of more power out of the same size injectors is turning up your base pressure. Injectors now a days can easily support the higher base pressures.
Also do not forget depending on the design of the fuel pumps more base pressure you run the less they flow.
