I swapped my turbo which had 80k miles on it for one with ~15k miles on it, both being OEM turbos. I also replaced the manifold and wastegate that came with the newer turbo, but now there's no boost being produced. I checked to make sure everything was connected, but can't figure out what the problem can be. I want to say that the new wastegate is not functioning properly. Anyone have any idea or dealt with the same problem before?
