RE: LOSSING POWER

I pull off the doser, the only two things connected was the power and fuel line, should I replace the doser, I have a brand new one but it seems to me its not even connected.

it throws a exhaust gas recirculation differential and Fuel filter differential pressure

If it is de-mandated, it should not be getting egr differential codes. Sounds kinda wonky. The fuel pressure code is likely something else. Make sure your fuel filter is not clogging up from algea or some other contaminant.

If boost pressure is falling off then check the vgt positioning in Insite. See if it is being commanded to do back itself off or if it is falling off and its position is stable. Also check the commanded position vs measured too when it is happening.

Check to see if fuel pressure is falling off too.

Also check the engine state parameter and see if it is saying it is in a derate.
