Sounds like carbon / soot / gunk buildup. Have a look at this post for tips - Sq5 diesel, feels like a misfire

It sounds rough. Black smoke & power loss after DPF/EGR/turbo/injector work usually points like below: Fuel pressure: Check rail pressure & injectors (even used ones can be faulty). Air intake: MAF sensor, boost leaks, clogged intercooler. Timing: Belt slipped/jumped? Check here above all and post them up for more specific pointers. Best wishes.
