Turbo actuator?

[Coelkfreak]

I had the code pop up occasionally ove the last few years and noticed no change in engine. Today it can up and the truck will make 18-19 pounds boost when I get on t it hard. Seems a bit sluggish. Usually if I get on it it will do 25 or so pounds. I’ve been ready alot and it hard to tell if it the turbo or the actuator? I would think if one or both went out I would make no boost. Ideas? 2016 2500 4x4.

Also I know City Diesel actuators is what most people recommend but has anybody used Circut Board Medics with the calibration tool

Thank Marty
