that's the basic run down. I know that the colors of the top of the injectors (GM only) tell you the flow rating. Those numbers are only if fuel pressure hasn't been changed from stock (~9psi). I don't know how much they flow if you bump fp up to say 12psi. I'm sure somebody has a calculation, if they do, please post.
