After my trip on MMS its time to reveal what happened.
After some discussions with Steve, and him finding out who owned the car previously, and looking at me oddly for requesting the the boost to be turned down, the final out come was....
I now have brembo brake fluid in the car, and the dyno done previously (and shown below) still stands. Apparently, thats what is needed for this engine/turbo combo to run happily, which is really the important thing.
The figures if their not clear are 440.7Nm and 212.5 Kw about 25000 Km ago, so no doubt its lost a few since then, but it still puts a smile on the dial.
The CEL although looking bad, showed up to be nothing to worry about, all was good when Steve checked it out.
Next mods are the AOS which is arriving via the group buy,
Some semi slicks, once I use up the existing tyres, (AHG/RAC this Sunday, Collie next Sunday should help that a bit)
Driver training so I can drive the thing effectively.
