Lack of power can be a couple dfferent things. One is you could have an exhaust leak that is causing low boost. The air filter can be restricted as well. Next you want to inspect the turbo vanes to make sure they don't have any damage to them. If all of that is ok unplug the ICP sensor and see if there is oil present. If there is oil I would replace the ICP sensor and connector. Next is you can have low fuel pressure. You can start by replacing the fuel filter and see if it helps. If that is ok a worn out fuel pump can also cause the issue. These are the items that can cause low power on this vehicle.

It has a new air filter, new fuel filter and the turbo was rebuilt at that time the exhaust was inspected. I will check the icp sensor.
Expert:  James replied 3 months ago.

ok, if the ICP is ok then the fuel pump is next so I would test fuel pressure.

Customer: replied 3 months ago.
Icp seams ok and I have already had fuel pressure checked and it's within tolerance

If the y pipe or exhaust manifold bolts are slightly loose this can cause low power. a bad MAP sensor can cause power or leak in the CAC system can also cause low power. How much boost is it building? DO you have a scan tool to monitor Boost?
