Raptor 150?
Will i benefit at all by installing a Raptor lift pump on my truck?
I only have a Superchips FlashPaq on it so far and straight piped the exhaust to dual 5,5" stacks

There is no "lift" pump in a powerstroke. Just a fuel pump.
However the stock fuel pump and system is good to about 238cc injectors. A small nozzle will help. Once you get above 160cc injector a regulated return fuel system helps the flow, but will not give you any more HP.
At 238-250cc injectors the stock fuel pump starts to struggle (and can at smaller injector sizes if its old, or has tank issues) but what most do is just add 2 factory pumps with a 5/8" pick up.
There are lots of great fuel systems out there for the 7.3, however none are needed with stock injectors.
