Rick08, any luck on this? I have been experiencing issue on my actuator also, it's a hit and miss, works well when it warms up but once it cools down doesn't seem to build boost. The last time i replace it was a year ago using a reman actuator and had to borrow a scanner from a shop and cost me $50 to calibrate. a week ago I decided to just pull the actuator with the key ON position to check if the vanes are sticking, by moving the lever and it was moving freely with very little effort, so i decided to order the actuator that City Diesel built which don't require calibration. Got it on yesterday and works like a charm.Update: As I mentioned, I tried installing the actuator without calibrating it with a scanner and no luck. After driving it a few times, my check engine light came on and showed a P226B code.(Turbo boost pressure too high) My exhaust brake doesn't work either. I contacted a mobile technician that has a Snap On scanner and I hope his scanner can run the actuator calibration test.
In the mean time, Launch hasn't gotten back with me.
