Do you know the fuel rail pressures that those flow rates are set at? If your ranger is flowing 18#/hr of fuel at maybe 40psig while the 12 hole injectors are flowing 23#/hr at 60psig, then they're not necessarily a larger injector.

It's used a lot in tuning if you need more fuel you bump up the fuel pressure to make up for smaller injectors.

Conversely, if you need less fuel you turn down the fuel pressure
