damn weird that some people are having issues with the new TB... can you explain in exact detail the surging your experiencing? are you dsg?
Yeah im dsg, it feels like since the adaptation fails, the TB is either shut or wide open. At low speeds the car bucks, and acceleration is choppy, 0-35 mph is hell. I also can hear the car bleeding off the excess boost. Cars also running rich to compensate.

Currently running Cobb Stage 2 Stock MAF 93 oct.
Attempted to run the first revision of my stratified map, but anything above ~30-40mph causes overboost and limp mode.
I know someone who ran the TB with I.E manifold and they have 0 issues. And yes I realize in this setup the turbo is now the restriction.
