just need a quick answer, im planning on running 7psi on my ls w/ the hack as fuel mgt. do i need to upgrade the fuel pump for this particular application? im worried if i do i will b running really rich since i dont have a fpr (which i could buy, but im kinda broke...). ne suggestions r appreicated, thanks.

 

i recomend that you replace the stock unit with a high flow fuel pump like the holley 255lph. I don't think your fuel pressure will go up with that pump (someone correct me if i'm wrong). I know the high pressure pump raises your fuel pressure but don't think the regular one will.

 

ne1 else?
