VGT/Turbo problems!!!

Hello follow site members. So I’ve got a problem. My 2013 3500 duelly Laramie longhorn is acting up. Sometimes when I start it up, put it in drive and try to drive off. It won’t go past 20 miles per hour. I turn it off and then turn it back on and it runs normal. With the fault codes I’ve pulled it’s saying the VGT actuator is not communicating with the ECM. So I need a new VGT!

my question is..... should I just replace the turbo as well? If so what turbo do you all recommend? Turbo/Actuator combo? Or should I just replace the actuator and be done with it.

My truck is stock. No delete.

I appreciate any info you are will to offer.

Thank you friends.
