Hi there I'm having a problem with my car. I had to replace the turbo core and the crank position sensor, since then the car hasn't run properly, it produces a smokescreen like a WW2 destroyer, the problem is slightly alleviated by disconnecting the vacuum capsule from the turbo (vgt). the manifold air sensor has also been replaced and the ecu tested. Can anyone shed some light on why it's overfueling? 

have had a vac on the turbo and it's pipework ie does it hold a vac AND movethe vanes    how's the egr/inlet and is the intercooler and pipeing  free of oil

Yes, the actuator isn't setup correctly for the new CHRA.

Yeah actuator would be a good start.

Thanks guys, I'll check it out and let you know how I get on.

Any recommendations as to a company that can do this?

The company that rebuilt the turbo but didn't set up the actuator correctly?

I rebuilt it myself.
