The only way I know of to see if vanes are actually moving is with a program that a person can command the VGT% and read EBP at the same time. (If I have read correctly)
With each change of VGT% the EBP should change also.
If you look at the pdf in the diagnostics area you will see what they are describing.
If you have heard a truck with the "vane Sweep" program with the latest flash. you can hear the turbo pitch change. Which tells them they are moving.
I don't have that flash. I'll see if I can find a video of the sound.

I believe the latest flash, and the one that does the vane sweep, was out in late 2009. I have it, I can see it sweep sometimes but I can't hear anything change. I am going to program in EBP and see what it says. I have heard that if the vanes are stuck you don't get a VGT code but you would get an EBP code, the computer would expect an EBP range and not see it. No idea if that is true, but you would also see boost range issues, over/under boost if the vanes were sticking, I think. Just a few minutes ago I was coasting down a hill and popped it into Tow/Haul to get some engine braking, and the VGT went to 35% and I got a lot of engine braking, when normally coasting off throttle it would be in the 65% range. Interesting stuff, figuring this thing out from scratch!

I can see anywhere from 15% -55% at idle with my strategy, it wasnt noticeable, noise wise, with the stock turbo but with a PM its really noticeable when the veins are sweeping, more so than the video.
I wouldnt worry about those numbers they seem perfectly fine to me.
