So I finally got the car on some UK rollers for a comparison run to the Aussie figures I had. Nothing has changed tuning or engine wise since the Aussie runs.
At 1.7bar with very conservative ignition timing (see ignition table) it made 511.9 bhp on V Power (98) at the flywheel. The car did 11.7 at 122mph on this tune on the quarter at York.
It's safe to say there's plenty more in it and 2 bar on V power with some more mapping I should get it into the tens on Vpower.
I didn't manage to run it on e85 and 2bar today but again the tuning on that map is also conservative. with only 13.5 degrees at the top end. Overall I'm happy as there's plenty more in it
It also looks like Aussie wheel figures are pretty much UK Flywheel figures.
Boost and AFR
Power and Torque
Here is the timing table. I asked for it to be mapped very conservatively for UK Fuel.
