F250: I replaced turbo on 2006 6.0l but still have a lot of

Customer Question

I replaced turbo on 2006 6.0l but still have a lot of black smoke and no power

Was the turbo damaged?
Customer: replied 2 years ago.
It didn't appear so but all things pointed there I guess, fins where a bit more rounded on old one. I can hear turbo threw exhaust at ideal now and I had lost that before. It's mostly noticeable at lower boost. It has no power and really blows black smoke until it builds up boost and then it's almost normal until u get low boost situation again.

I should also not there doesn't appear to be any cross contamination between fluids and I've also recently replaced erg valve and about 45k ago removed and cleaned tube and sensor on drivers side exhaust manifold. Recent on fuel and air filter replacements. I also do a lot of towing.
Expert:  Ray M. replied 2 years ago.
I would check the EGR valve again, it sounds like it may be sticking open, also you may have a bad MAP sensor.
Customer: replied 2 years ago.
Should I replace since its under warranty and map sensor looks cheap so I'll probably just replace. I did just notice my lower blue connecting hose up by radiator looks pretty warn but I can't visually see a crack but again looks very worn

I would remove the EGR valve and inspect it first, or if you can have it tested with the Ford IDS scan tool, this will also check codes, which should show up if the MAP sensor or the EGR valve are bad.

I do have reader and nothing is showing
Expert:  Ray M. replied 2 years ago.
If your scan tool can read sensor values, check the EBP, MAP and BARO readings with the key on and the engine stopped, they should all read around 13.5 psi and should all be within .5 psi of each other.
