I think I need to get an upgraded turbo inlet hose. When I drove around I could hear this air sucking noise (barely noticeable), which appears to be coming from turbo - turbo inlet hose. When I put in the VF34, I noticed that turbo inlet hose where clamp sits was worn out.
I think stock hose may be worn out or maybe I am mistaken for a noise coming from resonator removal mod since VF34 turbo is sucking more air in. I was planning on getting a turbo inlet hose anyway. It gives me another reason to write up a procedure for turbo inlet hose.
