Default vac leak at injectors

hey guys, so i have a vac leak at all 4 of my injectors ... probably bad orings from age

anywho, running the mods in my sig, do you guys think i should upgrade / change my injectors to a different cc? i can adjust fuel pressure with my SARD FPR....so it would have to be something simple and not overly different so my GIAC can still control and adapt

im jus trying to get out of the 210cc and duty cycle 16.23ms limit area, if i can offset it so i stay farther from 16.23ms then ill be happier

hopefully this can help alleviate the idling misfires i have

any thoughts?

thanks in advanc

Just change the o-rings. You wont be able to tune the injectors on a AEB car since you cant use lemmingwinks/unisettings.

Not even a little. The stock fuel pressure is at 4 bar so they flow more than you think. Also they can handle all the power you will be able to make with a ko3.

Not sure, but i bet anything that interupts the combustion chamber can cause a misfire.
