2000 f250 really low boost, no power, no boost leaks?
My truck seems to have really low boost. Averaging around 10 psi at 2500 rpm going 50 mph at a 6% incline. I checked for boost leaks with the homemade boost leak detector. Found nothing. All the IC boots are fine and not leaking. The intake boots are fine. The up pipes are fine. I even verified the boost gauge is accurate. So there's no leaks. Disconnected my waste gate vacuum line and it hit 15 psi. Any suggestions as to what I should do now? Maybe adjust the waste gate rod? Someone told me bad mapp sensor? I really don't know but I feel I should average around 20 to 25 psi.
