I will re-try brake boosting and have my dad listen in the engine bay. The front turbo connection I mention that was not changed, is between turbo and intercooler. As for the vacuum lines, I agree that it shouldn't cause this much of a loss of boost, but have seen cars do weird things due to small vacuum leaks. The lines I am mainly concerned of are the reference to the actual turbo wastegates. If that is disconnected, I could see one/both turbos trying to work on spring pressure.
With an IWG if you were leaking from the EBC to the wastegates you would overboost. There wouldn't be any boost to open the wastegates. Someone please correct me if I'm wrong.
If all of your lines are hooked up properly from the manifold to the EBC to the turbos, see if there is anyone local you can borrow an EBC from for a quick test. If you build boost after you swap it in there's your answer. I assume all Ecoboosts share the same 3-port. Maybe someone else can confirm?

You get that blasphemy out of here, I'm already scared as hell why its doing this, don't need a $500 dollar OE turbo to be the issue. There was a small amount of oil on the coupler from the rear turbo but I assume its normal, since it didn't seem like much.
I also have oil residue on the rear turbo inlet.
