Have you checked your FICM voltage or it could be stiction in your injectors. I had stiction and I changed to Rotella T6 5w40 and it helped alot with cold starts.

Agreed^^ check ficm voltage, do you have a monitor? Any codes? Egr valve? If so clean egr valve, check codes, and ficm voltage.

What did you use to check for codes?

I found this for checking ficm voltage.
