Injector duty cycle
ok guys, what are you seeing for duty cycle on your injectors?
running some data logs on my car (08 GT 6spd) seeing 98% duty cycle. so looks like i need to get some bigger injectors. first off my question is what size injectors are stock?? and have any of you upgraded yours on NA applications, and what did you go to. also what are you guys seeing for duty cycle?
just loaded in my Uprev software and going to the dyno tomorrow for tuning, but if im maxing my injectors out already i dont know how much i can get out of her right now...
my specs
Vq35HR
UpRev
Stillen gen 3 long tubes
Stillen headers
aam test pipes
tomei catback (y pipe and rear section)
Walbro 255

That seems like a very high DC on such few mods. Your car probably puts down over 300 at the wheels though?
I was maxing out my injectors with 98-101 DC and ive upgraded to GTR 570cc injectors. I beleive a lot of my issue is my fuel pump its from 02 and has 200k on it.
Id be very interested in seeing what #'s you put down, as i though HR's had enough injector to support n/a mods easily.
My car isnt supporting my power lvl because im up about 100whp over what the car was in 100% stock form.
