What was the fix for this problem? Currently fighting a 15 6193 is truck that is having the same issue
I know its been even longer since your last message haha, but im having what seems to be a very similar problem with my '15, but, I bought it deleted 60k ago, and its been perfect, until thursday, and now its acting like whats described in the forum, desired and actual boost and vane pos are the same, so it leads me to believe its electrical, its like it was flashed back to a stock file but without emissions, im only working off a cts3, no hardware from whoever tuned it, is it possible something happened in the ecu? No codes either, at least what the cts can pull
my turbo vanes were sticking split turbo and cleaned works great now
