Trying to track down why this code keeps popping up, assumed it was a leak causing it had the car smoke tested (came back no leaks) and even bought new couplers for the turbo system and changed any o-rings as well. Only happens on the top end, can't tell if maybe I have a faulty TMAP or something all the codes point towards that hoping someone has had the same issue and figured it out, mods and log below

I know this post is old but did you ever figure out the issue? I just ran into same problem and we have very similar set up.
