Plug ,plug wire , knock sensor?

If the view you see from under the car is bigger than the size of a silver dollar,then you might need a new cover because the old one fell off.
If your having trouble finding one you can cut one out od sheet aluminum.
Use a piece of cardboard as a template then place it on the sheet aluminum so you can get a good fit.
Add the holes and bolt it up.

Is changing the waste gate all you did? Did you change anything in the air intake system? You must be very careful altering the boost pressure on turbo cars. You can cause the engine to detonate and blow a piston. I'm not sure what the rcommended boost pressure for your model is, but it is usually between 1.5 and 2.5 bar.
