Click sound on first stop could be floating calipers, which are probably operating as designed. When you back up they move back into position and click when driven. Again, this is normal behaviour.

Empty and change your diff fluid, gearbox fluid and transfer case fluid. When the fluids are out and in the pan, run a magnet through each to see if you can collect any metal pieces.

It is quite likely the work performed has introduced a subtle air leak that only manifests itself under high boost. Pressurizing the intake tract with the car off will help you identify the source of the leak. A hose fitting that isn't honked down all the way will exhibit this kind of behavior under boost. I like how Jafro figured out the source of his ...
