head scratcher

Good morning everyone. I have a 2002 F-550 with 7.3. My problem is I can start the truck just fine. It runs fine at idle no smoke or anything. But when I go into 1st to second there is no problem so now going from 2nd to 3rd I get a lot of white smoke out the exhaust until the turbo spools up fully. Then no smoke from then on only 2nd to 3rd... any ideas on this?? Also there are no codes whatsoever

I think little bit more information is needed. Is this an auto or a manual transmission? Any leaks around the turbo?

It is a manual transmission no visible leaks anywhere. I pulled all injectors prior to this because I thought maybe it was injector O-rings. All the O-rings were fine but I replaced them anyway since I had them out.

2-3 is a big jump, and the 550 likely has 4.88 gears in the back. What RPM are you shifting at? Any change if you shift at a RPM that is several hundred different?
