Damn, now thats quite a bit overboosting there *g*
BIG ? for me without seeing the file....maybe boost sensor linearization is wrong?
In fact it looks like there comes no mechanical reaction from vnt mechanism, dc shows that it trys to reduce boost (94,4%, full open vanes) but seems like the vanes dont move....
What did boost gauge show?
4000mbar in log = 3bar ;-) not 4bar.
