I have a 2000 7.3 that only builds 16 pounds of boost, i have got to near smash the pedal to the floor to build any boost at all, the truck really lacks power! i was looking at it last night and noticed there is a leak @ my y pipe on the back of my turbo i tore into it and hope to get it replaced today! my intercooler boots look ok! i sprayed ether around them and the truck didnt rev up? dont know if this test is sufficient? i have been told there is a waste gate upgrade to get the turbo to put out its max 25 psi? i have a BD 6 position programmer, 4" down pipe, 5" straight out the back, air raid intake, boost fooler,do you think injectors could be my problem? not enough fuel?? I have been told the early style van turbo is a better turbo & can build over 30 pounds of boost, is this turbo better than a SD turbo?? Any info you could give me would be a grat help> I have got to figure something out the truck is just worthless the way it is?
