Would an after market fuel rail and fuel pump help out a lot if the stage 2 is installed? How do they go for and is it worth it?

 

it's not needed with stage 2 really. the injectors that come with stage 2 are pretty big already, and the car runs pig rich as it is. the fuel pump isn't a bad idea, i'm going to upgade mine to a 255 soon, but the fuel rail is really not needed.
