Black smoke on acceleration, low boost

06 just started blowing black smoke at acceleration, takes an extra second to get power, and not much boost pressure. Any ideas?

Inter cooler boots ripped? Sounds like you have a big boost leak.

I'm assuming you have your truck stock witg the egr valve, I would say your egr valve is stuck open.

Easiest check is intercooler boots and pre-turbo exhaust leak

Only 4 things:
Exhaust leak pre turbo,
Charge air circuit leak,
Stuck vanes (wiring or mechanical), or
PCM issue (ebp, fueling, egr, map).

The first 3 are most likely, the last is possible. It is highly unlikely you have gasket issues or turbo damage.

What are your gauges reading?

Are you running a performance tune of some type? Was it working well before with the same tune? If your vanes are not closing soon enough or your PW is slightly larger, the punch test will show smoke. Same goes for a minor boost or exhaust leak.
