After a few weeks break I took another look at the leaks, and replacing one dodgy 45* -10 fitting and two gaskets seems to have made quite an improvement.
I made a new CAS bracket because my first one didn't have enough adjustment in it, the new one has no adjustment at all but shouldn't need any.
Then I put it all back together, dropped it off the stands, and drove it out of the garage for the first time in months.
The turbo has quietened the exhaust down a lot which is good, and it appears to spool up pretty quickly from my limited testing on my driveway.
I thought I'd try to work out my correct reference angle while the car was out of the garage, so grabbed my timing light and commanded Mode 4 20* advance, but was seeing a lot less than 20*.
I assumed my reference angle was way out so started adjusting it, but then I noticed that with mode 4 cancelled the timing increased on the pulley marks, but it should have been the other way around.
I was a bit confused, and later when I was looking at the log I saw that when 20* was commanded it only held there for a few seconds, then dropped to 2.5* which would explain the roughly 10* increase I saw when cancelling mode 4 timing:

Here's the log and bin, I'd love to know what's going on here...
