Every truck responds differently.

Every tune will do something different in a different truck.

I'd the tune you have is smoking like that then the truck may not like that tune.

They make different versions of a tune and if you got the support pack then you may want to try an older version.

I have found that the 2.0 & 2.1 smoke more than the earlier ones.

If you have the 4.0 tunes you can adjust the fuel settings and that might help.

But, if the guy who installed them holds the tunes you need to get him to do it.
