    Hello I have a 2011 Volvo 670 I just replaced intake sensor, turbo speed sensor, injectors and cups, full service, fuel filter housing, fuel pressure sensor all done at volvo dealer in Windsor, On. Only codes coming at dealer are coolant level sensor and oil temp sensor I will be replacing the coolant level sensor when i get home and oil temp sensor at next service. I am getting horrible fuel mileage running at 5.2mpg right now. I did an egr dpf def delete to this truck. The problem I am having is very low boost either loaded or empty. I found a small leak on the exhaust side of the turbo will be replacing the clamp and gasket when I get home. Can anybody tell me what may be causing this.

    Check for an air to air intercooler or plumbing leak including the air compressor intake.

    So I checked the air to air had it tested at the dealer changed all the hoses and clamps O rings and gaskets on the air to air as well as fixed the exhaust leak on the turbo but I still do not get no more than 15psi of boost. turbo actuator passed test at the dealer as well. any suggestions would be awesome this truck does not leak any fluids or air seriously at a loss at this point.

    I bought a reman turbo and the turbo was defective the exhaust compression wheel was 1/4 inch small in radius put a new compression wheel on and turbo works good. Before that we had leaks in the intake manafold the gasket there is a very cheap make and gets blow out.
