I'm also having an issue with the dreaded ECM-6805. I only get the code when the engine is cold, never when warm. When looking at the data from VIDA, it shows that the VTN actuator opens up 100% very easily when the engine is cold, and this creates overboost. When the engine is already warm, it usually doesn't go over 80%. Has anybody had similar issues? Could it be a sticky turbo?
