high volume fuel pump?

while browsing for grand prix mods (as I always do), I came across a page saying that a high volume fuel pump is required for higher boost levels... I suppose such as adding a smaller pulley, etc...

so, since my fuel pump is now buzzing/humming louder than my exhaust, I suppose I might as well invest in one of this "high volume" ones. sooo, where would I find a one? will a Pontiac dealer have any clue what I'm talking about?
