Does the smoke clear up quickly? If not, check your wastegate operation.

It's fine then. When you punch it, the turbo is not spooled, causing over-fueling, and that causes smoke. As soon as the turbo spools, the air-fuel ratio evens out a bit, and the smoke clears.

No problem. I read at this and other diesel sites. Probably more than 90% of what I know I've learned here.

So, My waste gate isn't working correctly since mine still puffs black smoke untill I let off of it? ... Looks like I'll have more work after I'm finished with my fuel tank flush ...

Check the operation before saying for sure. I think you can find how to check it in the FAQ's.
