The boost issue has been resolved. The root cause was a faulty wastegate actuator. We replaced it, as well as the ebcs and the turbo inlet pipe (which had a small tear). Boosting like a champ now. The turbo itself was fine. It has less than 10,000 miles on it.
I uploaded a log I took here. I did not install the tune yet. I received a base map to install, but am holding off installing until the boost issue is resolved.
Newbie here. I have a 2010 MS3 with about 114K miles on it. I bought it used and have owned it for a year. I am not a mechanic, just an owner. I've had a local reputable shop do a lot of work on it to back out some poorly done mods by the prior owner, and to replace worn out parts. I'm happy...
