Default Bigger injectors

along with my twins that i ordered, i also purchased the stage 3 100hp injector nozzles with it. should i see a drop in fuel mileage with those? or was the stage 3's a good choice?

Keep your foot out of it and you should notice no change or maybe a little rise in milage... Bury you foot in the throttle and watch the milage go away.

yes they are meant to handle more pressure, but they will also use more fuel as you are going to an injector with a higher gph flow... just dont drive everywhere with your foot in it like stated above, and you may even see a gain, depends on how good fuel pressure you have, and how good of fuel atomization your getting...

Please dont take this the wrong way, but if you got twins and bigger injectors, why would you be worried about fuel mileage?

i wasnt worried about mileage until my first reply was a message stating that my mileage was gonna be bad. and i have to stage 2 cp3 from industrial injections. hopefully my rail pressure is ok. i dont have a guage but i dont think ill have that problem.
