A 97 sunfire Circle track car. many mods and now running out of fuel injectors.We are at 100% duty cycle for a long time and leaning out very bad. After installing a top feed rail and getting the throttle to clear now I get to HPTUNERS and there is only an adjustment for INJ. constant.

I am going to locate some ford injectors today.
Is that all I need to change is the injectors and constant? and all will be good?
