Hello after exchange Turbo I got error P0079 I can't find anywhere what is problem :-( pls help.

 

Because you did not mention any running condition problems...
Changing your Turbo should have cause this DTC. So my first suspect without knowing more details about the overall condition of your engine would be to; Clear code and run one engine cycle and see if it returns.

Properly clearly the code is to use a quality diagnostic scanner connected at the diagnostic connector of your Mazda and clearing the code. Also go to monitors and check their readiness state.
