Flowrate is measured at how much fuel an injector flows at an industry standard 43.5 psi, because the OEM injectors are older needle style injectors they do not atomize as well as a modern 4,12, or 18 hole injectors so they shoot "two streams" which is a dated technology. The game nowadays is how fine/dense of a mist and small the particles of fuel can get. The fuel rail/fuel pressure regulator controls this ~43.5psi condition for the injectors so flowrate can be varied to a certain extent when increasing how finely the fuel is atomized. My understanding is that as we increase the atomization efficiency and mist density of fuel in the motor we can safely run a slightly larger flowrated injector. The ECU cannot physically see the larger flowrate but because the difference is not much it compensates in the fuel table. I am running a Uni-Filter, DF scoop, and full SOS exhaust setup, so i believe these modifications make the case for larger injectors even more convincing.
Any luck on this? Looking to do rdx injectors but not finding anyone that still offers the ecu prostreet tune or harnesses.
