my friends stang has 30lbs injectors and he had to run 20psi to stop the hesitating.
are you sure it is not water/condensation? i find it hard to believe that you spewing fuel out the pipes.raph130 said:yeah i can literally see fuel spraying out my 3 inch tailpipes all over the cement. it accelerates likes crap. time to order a kirban afpr. hehe

good luck.
Michael Yount said:raph - if the maf is calibrated correctly, it "adjusts" for the larger injectors. The maf and the ecu are both expecting to see stock fuel pressure - 38-40 psi measured at idle with the engine warm and the vacuum line off the regulator and capped.
The ecu has adaptive strategies - it will adjust things to try and keep the a/f ratio in a range that's designed for best emissions. You can increase or decrease the fuel pressure - but the computer over time will simply decrease or increase the injector pulse width to get the a/f ratio back where it's supposed to be. You turn the pressure up - it simply holds the injector open for less time; you turn it down, it simply holds the injector open for longer. And, it will, over time, also make adjustments to the wot tables as well.
So, as long as your maf is calibrated for the 24# injectors, leave the fuel pressure alone. You're not gonna accomplish much of anything in the long run playing with it.
