Engine/Transmission (1998.5 - 2002) Everyone running dual Carter lift pumps (helper pusher pump) chime in - any failures?

So Andrew, if my stock pump is pushing almost 15psi it must be the same as the p4601hp. So can't I just leave the stock one and put the new p4601hp in the back? Or will that double the pressure? Or what would be the pressure if I put a p4600hp(7psi) in the back and left the stock pump in? I don't want to change to much in case I need to remove things. Thanks for the help.
