So I have noticed a power loss in my 2003 7.3L so I decided to pressure test my pump and heads. So I dead headed my pump and came up with 3900 psi then drivers side pressure tested at 2000 psi then the passenger side only got to 1100. So I decided to get into the injectors on the passenger side I pressure tested them to see if anything was leaking by the poppet valves all the rail drains all that was good. Started pulling injectors and changed orings with Ford rings ( injectors installed 14,000 miles ago) put everything back together get the truck started clean it out let it run sounds good no different then before get it hot go for a ride come back run a pressure test on the passenger side again and I still have the same thing what gives I should be at 3900 or close to it RIGHT. I'm lost
