I have a 2004 MBE 900 that won't build boost pressure. It was originally brought in for head gasket leaking. Replaced head gasket and installed refurbished head. Now it won't build boost pressure. CAC has been replaced due to leak found during pressure test. Turbo has been replaced due to actuator sticking and pressure sensor replaced due to soot build up. Anyone have an idea of what else to look at and find the problem?

check for a rag or some other thing that can block the hose if it happened after you fix it it might be something you did been there

I checked exhaust and it's not plugged. Also checked the EGR valve for proper operation.
