.What Is My Turbo Actuator Doing?

The emissions output, the turbo, the EGR system, and everything else is still factory set as a 'closed loop' systems, where when it will try to control sensor 'Inputs' instead of meeting 'Outputs', with regard to all these systems, making it somewhat unpredictable in how it operates at any given moment.

Yeah maybe I'm just chasing shadows. I now can't unsee the changes in pressure throughout the day. I recorded again. Only thing I added was actuator commanded position thinking that maybe it was getting hung up, but it looked good and matched up. Got the 2 psi back. Thank you for that.

For peace of mind, I did both fuel injector and air handling performance tests and they passed.
