2007 Cummins ism issues

[race7820000]

There is no codes at all,
I took off the actuator? The silver thing. I can't move it even if I press it on the floor lol

The part of the turbo that it bolts to moves super free and there is air coming from the line that goes to the actuator (silver thing) when it's running.

The turbo was replaced before I got truck 100k miles ago, there is no play I can tell in the turbo at all.
