Brothers truck shut down on him and is throwing these codes, overboost,underboost and two egr related codes. Truck has an EGR delite in it. I'm thinking bad turbo. any ideas?

Any symptoms before it shut down or it just died?

He said it just died. He wasnt driving the truck at the time and I havent been able to talk to the who was yet.

See if you can get some more info, and post up his year and model and any mods, is he running any tunes? May can get a better response with that info from one of the techs on here

In every case of 0299 I swear it seems like every person has had to get a new turbo after posting they had that code. I've seen a lot of 0299 threads and seems like the OP always ends up coming back into the thread posting that he had to have the turbo replaced.
