I wasn’t actually talking about the turbo being the problem. I was wondering what the pressures were to rule out something in the air supply side.

Sounds like it is overfueling for whatever reason. How do you know your injection pump is ‘fine’? Thats pretty damn vague. Sounds like something in the governor system (I assume it is electronic)is out of whack—like an air/fuel ratio control or whatever kubota calls their electronic version

We replaced the pump with new oem, we plugged into the wire with adapter to get reading from pump. We have also checked the throttle body and it checks out fine too.

Pretty much why I am here, I have nowhere else to look engine side of things.
