Thanks again.
Saw the off-road vacuum line pics during my initial search and have already started the process by plugging and disconnecting. In the second photo, what is the line with a blue vacuum cap? I didn't notice it in the third photo.

Back to my turbo issue . . . when the vacuum source (bypassed the Y30) was good to the ALDA my power increased. Would this not indicate the turbo is functioning? It's been a long day for me so possibly I'm just in brain drain mode (my wife marvels at those moments).
