2004 e350 6.0 Rough start loss of power HELP!

On a cold morning start, my van ran very rough, alittle white smoke and sounded very flat. Has had a power loss ever since. Starts fine and runs in park ok, but turbo does not seem to be working much. Drives but no power. (cleaned and checked turbo)
and has egr delete. New fuel filters. What could be causing this condition. No codes and just happen when starting it cold.

do you have a way to check FICM voltage?

Ok I found the problem! The exhaust back pressure sensor seems to be bad. It wasn't easy to find on my 2004 e350, when I took it out it was full of carbon so I cleaned it and the tube. Re installed and it did not work. Unplugged it and now the turbo works. Question is can I drive it with it disconnected without hurting anything? The turbo sounds louder when you let off the pedal
Thanks.

you can try cleaning the sensor and the tube out and seeing if that makes a difference

Ok here's where I'm at. I replaced the EBP sensor and it ran so good for about 30 miles. Then loss of power again, but this time the turbo still has some boost up to about 25mph.
I can unplug the EBP sensor and it runs good but doesn't sound right.

did you clean out the EBP sensor tube off the manifold?
