If that's not enough for the shower, it may be time to consider a different shower head and/or to check for anything that's restricting flow. My fresh water pump is only good for 3.5 gpm and the pressure switch cuts it off at 40 - 45 psi. And I rarely turn the shower on fully (and when I do, it's more than enough flow). IMO, more than that is a great way to chew up a lot of water very quickly, so I'd be cautious about going to a super high flow system.
