Ive read over your posts and you haven’t mentioned checking out your fuel tank strainer and your two fuel filters. Sorry if I missed it. If you haven’t you need to check and replace filters. This is a must when acquiring one of these diesels without a maintenance history. Top end power issues scream fuel filters to me.
I got my 300d with low power. It was really neglected. It was different though, it was weak off the line but had good top end power. I did all the basics boost line, valves, fuel filters, timing, rack damper adjustment, linkage adjustment, cleaned sticky turbo, removed clogged trap oxidizer. It seemed everything gave it some power back. Now it is a pleasure to drive and drives normally.
Then after all that, I tested my injectors. They were perfect and I put them right back.

He did test them, I called him, he said he has a machine for it, his English is fairly good but he doesn't use some of the terms that others use. When I told him I was thinking about getting them tested he said to bring them in as long as I have them out, he'll show me. Will do that in the next couple of days.
Oh man, rust. I was having huge trouble with the primary filter clogging up in short order. I was taking them out almost every day to clean them with WD-40. Probably other ways to do it. I bought about 4 or 5 before I realized I could clean them out. I also replaced the secondary filter.
I finally took the tank out and cleaned it. Used purple degreaser, acid, pea gravel. I think I did it about 95% effective, if I did it over I might have done a few things better but it was a huge improvement. I put in another new secondary filter. I had a thread about maybe putting in a new tank.
Here's the post after I pulled it.
I've done a few other things as well. New oil cooler lines. THAT was a tough job. One of the existing was leaking, not a small leak. My Mechanic, Ky, spotted a badly worn fan clutch, put in a new one. If you're ever in a bind in the Bay Area: Ky's Auto Repair, Redwood City, south of SF, north of Palo Alto.
