Start up and drive down the road it has no power like it's going into limp mode. A week before I changed the turbo I changed the compressor on the air conditioner.
The only codes are showing is
MAF circuit B1
TC System B1
What would be my problem?

So if the turbo went out there was probably oil inside the intake which damaged the sensor. I would confirm the oil inside the sensor and then replace it, you might be able to clean it but I have not had good luck doing that. The MAF sensor can affect the traction control as well.

MAF Circuit B1 (Mass Air Flow Sensor Circuit Bank 1)

TC System B1 (Traction Control System Bank 1)

Here is the location of the sensor so you can check it out. Check out the images (below). Let us know how it goes.
