When to use bigger fuel pump?

[Apex Man]

At what boost level must I use a bigger fuel pump running on flat land? Is the Ford pump only for higher pressure? How about current draw compared to stock pump? How much for the fuel pump kit? I'm using 3 stacked head gaskets and I'm unsure at what boost to run with my supercharger, 5-7,8-9 or 10.

Thanks

After reading around these forums, I believe a bigger fuel pump is needed at 10lbs and up.
