Diesel Bombers - Freshly rebuilt engine has no power

I have an 04 LLY fresh off a rebuild bored 20 over, 63.5mm turbo, 15% over injectors, ppe manifolds and up pipes, max flow down pipe, pusher intake y bridge and pusher diver and passenger boost tubes, fads fuel system. The engine was take out cleaned and everything that is a wear item has been replaced, now it is running and sounds great but it is burning oil as well as coming out of the exhaust and it has no power at all. I know i should but a little oil as the rings seat to the freshly honed cylinders I’m more concerned as to why i doesn’t have any power.
