So i have been doing a lot of research on new injectors for my turbo project i have come to the conclusion that I am going to get 34Lb MSD injectors. Now the question at hand is if i install the injectors into the vehicle (before installing the turbo) with my FPR i know i will be able to raise my fuel pressure slightly without putting to much stress on the new injectors or clipping them. i was just wondering if the duty cycle will be affected by the new injectors, or is the higher flow rate just due to the larger diameter of the injector itself ? Also is the duty cycle just changed by the FMU ,hence why you need one to adjust for the extra fuel after the install of the turbo? Hope these questions aren't to No0B-ish. Thanks for any input... unless i get flamed
the electrical signal will not change just by changing injectors, the injectors will be open the same ammount of time.
If you install larger fuel injectors, by 50% they will flow 50% more fuel at the same duty cycle. ex, if you had 100cc injectors before at 50% they flow 50cc, if you just simply installed 200cc injectors they would flow 100cc @ 50%. so you would have to turn down your idle fuel pressure, or program the PCM to lower the duty cycle.

and i didn't think that the bosch green tops were high impedance.
