You still need to replace those 2 injectors. The intake air heater doesnt really matter and the boost thing is related to some sort of issue with your turbo.

Cylinder Contribution

Ran the same tests on mine and got the #8 balance fault also. P 0284.
So does this mean the injector is bad, or could it be the injector harness under the valve cover?
