Couldn't find any vids on the 2.8L, but here's something from the 2.5L to put you in a frame of mind of possibilities

We done this Chevrolet Colorado together with Peak powershop in Bangkok.
The engine it self is standard including the injector and hi pressure fuelpump. The only modifications done to this engine so far are the low pressure fuel feed system and turbocharger.
We mange to get a lot better engine response and where able to pull out 350Hp and 700Nm (500 lb-ft.) for a short time as the commonrail pump can not supply the fuel pressure to support this power.
Also a other type of turbocharger is needed and we hope this will give the engine a lot more low end power as we could not run a lot of boost in the low RPM as we where hitting the surge line of the compressor very hard.

The 2.5L Duramax is rated at 150hp/258 lb-ft.
