just got a cummins, have some questions

removing the fuel plate makes the pedal control fueling to whatever the pump will allow without rpm input.
The AFC adjusts how much boost affects the amount of pedal input to fueling vs boost. It will hurt mileage if you push the pedal down to make smoke with no boost. Some people gut the AFC and make it just pedal input, some people fine tune it and make it work how its supposed to but with performance in mind.
That being said, no plate and star wheel cranked has made smoke hard to control when you have to roll off a red light with a cop watching you.
The star wheel adjusts preload on a spring that holds tension on a diaphram that has boost pushing on it. So the more you load the spring with the wheel, the less the fueling depends on boost.
