Is my stock fuel pump limiting me in HP in my 408? I currently have a stock fuel pump, stock rails, and 42 lb injectors.

Do you have a fuel pressure gauge?

Might be a good place to start investing Also 255 pumps are dirt cheap.

I remember reading somewhere that the stock pump can only support around 430-440 RWHP. Is that true?

If so, I need to upgrade It seems like everyone suggests the racetronix since it is plug and play. Any other kits that are plug and play?

I really dont know much about the plug and play kits - i trashed my entire oem fuel system and went with external pumps.

You should probably get a fuel pressure gauge, 255 pump and some injectors

i got 470 rwhp out of my stock pump on a 150 shot but i'm sure it was maxed out and some pumps may be alittle weaker than others,i would get a 255 and be safe.
