I will do my best to assist you. please keep in mind that I may need to ask questions of you before I can answer. When you reply please feel free to add as much detailed information as possible pertaining to your concern.

Have you checked the intake system and Turbo Resonator for intake boost pressure leaks?

Customer: replied 7 months ago.
well i just saw this problem. how do i test it
Expert:  Robert replied 7 months ago.

Basically if there is a leak, you will find oil vapor spray near the leakage point. On the intercooler hoses, just check carefully for splits or tears. The turbo resonator is at the turbocharger outlet., If this is bad, you will see oil spray on the hose that runs in front of the resonator. You will also hear an air rushing escaping sound under hard acceleration before the turbo stops boosting and goes into limp mode...

Keep me posted...

Thank you,

Robert

i just replaced the resonator and we are still havening the same problem. The intercooler hoses look good. is there a way to test for leaks?
Expert:  Robert replied 7 months ago.

To test for leaks you can have a helper "Power Brake" the engine in reverse while you listen to the intake air system for leaks. You will normally hear a loud air rushing sound coming from the source of the leak...

Keep me posted...

while i can't really tell when we do that i do have black smoke dumping out the exhaust. what are the signs of a turbo that shit the bed?
Expert:  Robert replied 7 months ago.

Just pull the intake hose from the air cleaner housing off the front of the turbocharger and look inside. If the turbo compressor wheel is damaged or "Sand Blasted" then the turbo will need to be replaced...

Here is a pic of a Turbocharger that ingested sand and notice the blades are rounded off and sandblasted..

If yours looks similar to this, the turbo will need to be replaced....

it definatley does not look like this. is there a way to test if it is working?
Expert:  Robert replied 7 months ago.

If you are getting turbo boost until it goes into limp mode then the turbo is definitely working... If you are certain that there are no leaks present, then I would go ahead and replace the Boost Pressure Sensor (MAP sensor) and possibly the Mass Airflow Sensor.

Keep me posted...

Thank you,

Robert

Customer: replied 7 months ago.
Which one is the MAP and which one is the Boost pressure sensor? where are they located
Expert:  Robert replied 7 months ago.

I'm posting a pic that shows the location of the Boost Pressure sensor (aka MAP Sensor). The MAF (Mass Air Flow) sensor is mounted to the Air Filter housing and the turbo inlet hose is attached to the MAF sensor.

Here is the Boost pressure sensor Location:
