Yeah I think the next best thing is to actually properly tests it for a boost leak and go from there. Is it possible for a turbo to be bad and not build proper boost without making noises? It has the factory turbo on it still with 135k miles.
I find it very interesting that on the fine learning knock correction I get just a little bit on 2 lines and if you follow over to my boost level it has a hiccup and fluctuates up and down right at that moment. That may be a normal thing for knock, I'm not sure.
