the Type S goes on with the bottom of the valve facing the pressure tube. Bad thing about the S is that you must set it correctly. If set too soft you can have a idle issue and you will not get full boost. If set too stiff you can get compressor surge which can cause the turbo to fail.

Enough so it doesn't open and not too much that it causes compressor surge.
