Usually, older diesels blow some black smoke till the turbo spools up.

Well it aint gonna go away haha. Diesels blow black smoke... totally normal. You should see mine.... If I were to use my race tune in traffic the road would be so black for 100 yards that traffic would stop lol. Hence why my race tune stays off the street. A little smoke like that is normal for a truck tho.

Get some good clean efi tunes from IdahoRob and it could help to clean it up plus improve your power and MPG
