Dont know whats goin on with the truck but mine would pass cal just fine then quit throw a code and derate pulling out the driveway. Again i dont know if ur having problems or what they are just .02 to think about.

Boost and pyro gauges are your friend. Especially when you suspect they are getting out of calibration.

I have seen a few trucks that had calibration issues. It usually starts out where the turbo will over-boost or under-boost depending on the last time it was cranked up. Shut the truck off for 2 minutes and re-start it and it acts normal again.

turbo does a span check each time the truck is started up. It then uses this span to position itself. If it is hanging up, the span suddenly becomes different. Its too bad the manufacturer was too stupid to include a raw span measurement value that can be read by the ECM/Insite so that you can troubleshoot common problems like this eh?

I have often thought of adding a small hole (tapped with threads and a plug when not used) in the side of my actuator in line with the gear so that I could insert a measuring tool for its position. that way it can be mechanically validated without having to take anything apart.
