Still trying to work out why boost is so low (14 psi) Went back into the shop that rebuilt my injector pump to trouble shoot. The tech connected a very nice oil dampened calibrated gauge to the turbo actuator and we saw 18 psi with the actuator rod only starting to move at 14 psi. He then connected it the the rear of the intake manifold where my Autometer gauge measures from and it showed 14 psi, the same as mine shows. Somewhere between the turbo and the intake manifold 4 psi is being lost. We couldn't find any leaks any where. Is this pressure drop normal? People with the same turbo showing 20 - 21 psi at the manifold, what have you done that I haven't? Rather frustrating that a bolt in kit is causing so many issues. I also found a small leak in my expensive radiator, so super chuffed about that. The pics show the actuator and fitting at the rear of the intake manifold where we measured from, plus the leak.
