I had the same problem. I played with the actuator arm up and down, replaced all hoses with new oem ones and nothing seemed to work. Finally, I took out the restrictor pill from the hose that goes to the turbo and replaced the hose with smaller diameter and my oscillating overboost went away. go figure!
