Great analogy about the cow!!
If you install injectors with higher or lower fuel delivery rate from the ones that you are removing, you need to reset the ECU so that it will relearn the relationship between how high the duty cycle is and how much fuel is delivered. If you stroke the one teet 2 inches and get 4 ounces, and the other 2 inches and get 6 ounces then you know it will only take two strokes of the second to fill a 12 ounce glass.
