Is the line to the turbo control valve accounted for? The "Blue" line on the turbo control valve winds up on an intake manifold port but I can't remember exactly where it plugged in on mine.

I'll check again but I'm pretty sure it is, thanks Lee.

It's a little more confusing because I have a full SAS delete. I ended up plugging the line coming off the green star check valve (pictured below) and running the yellow star line to above where the green star check valve line ends up near the PCV valve.

Drove it around the block a few times and it seems to be running great with no codes. Before I did this job it was throwing P0172 and P102 within a few seconds of clearing them.

Thank you, thank you, thank you. I have been searching for these diagrams for 5 years. I actually ended up replacing all of the inter-cooler hoses as they blew on my first 1994, 850T. Alas, I moved and could not take that one with me so I bought a '97 850T when we settled in our new home. On this one, the turbo gauge never gets past the middle of the black part, but it isn't slow. I am going to check everything out from these diagrams. Thanks again, kimothyanne.
