In theory you could lower the fuel pressure and make the car a little leaner to gain some power, but that's a pretty crude way of doing it. Coupled with all the fittings it would take, it's likely not worth the trouble.

yea they had it rigged up to the car before i took it off

this is true, i did this on my na. ran the fuel like reteds parallel setup. big difference i noticed is that you have to make a custom secondary fuel rail. this is becuase on the s4 the fuel pressure regulator is bolted on the side and is not a screw in. i lowered the fuel pressure a tiny bit and felt a little difference in the butt dyno but no real numbers. my intetions were to use this setup coupled with a wet nitrous system. so that the fpr would also help maintain fuel pressure in the soleniod.
here are some pics from the project
