Good luck with the search. I was amazed at getting my 300d back to making power. It wasn’t any one thing that was robbing power. It was half a dozen things each eating a few HP and once I went through it all it finally ran properly.
Putting a boost gauge (just a T, some hose and a cheap air gauge) on my ALDL line gave me an idea just how much boost I was getting. I had a lot of goo on the inlet side of my turbo.

Is that something that needs attention?
Speaking of goo, I pulled the ALDA line from the manifold, that was on advice from this one:

Oh man, not sure I'd call it soot, but it was black and residue like, that's certain.
I got the right size drill bit (loose fit) and cleaned the junk out of the long skinny part, then used WD-40 and brake cleaner to clean the rest and the line as well. Blew compressed air through it. Good thing I found that. My fix of the other broken line probably wouldn't have gone so good.
One thing I wonder about is the little relay hub where the lines converge. Tonight, to take off the manifold banjo bolt I took the hub/junction off the firewall as I couldn't see where that hose hooked in. I noticed an electric line coming off of it. I'm curious just what goes on in that little hub thingy.
