159 2.4 mjet black & white smoke

hey guys i really need help with my diesel engine.
the problem start when the car lost power specially when i drive up the hill,i clean the EGR and the throttle body from the carbon and replaced the Boost Sensor. BUT no luck.
then i decide to check the turbocharger, i fit new CHRA.
After that the engine start smoke white (un burn diesel) !!!!
Then i start play with the INJECTORS and end by replace 2 new injectors and write the new code to the ECU.
after that the engine start smoke Black.
Then i play with diesel pump timing to reduce the smoke.because the injector NO 4 value was 5mmi.
after rotate the Diesel pump the value reduced from 5mms to 2.3mmi, but it still smoke white and if i accelerate it smoke lot of black.

i attached the last reading from fiatecuscan.
hope someone can find out what going on
