It is normal for this to happen when you load a tune into your truck. It comes from the increased rail pressure and it takes a few minutes to bleed off. It doesn't cause any harm to the engine. It does it slightly even in your stock tune.

It also has to do with the third injection event on the 04.5 and newer trucks. Mine does it also, many searches on the net.
