It's not had it's final session yet, but made 162bhp on that run.

What did it make at the wheels? Ie what percentage transmission loss was used?

The coast down losses are measured along with power at the the wheels, then power at the flywheel is calculated.
I'm not sure what was measured at the wheels, that figure wasn't offered...I can try to get that when I go back to finish it off.

I am quite intrigued but everyone's obsession with bhp which is a measure at the crank.
If you take two cars that are identical in every way except for the transmission losses you are going to get a difference in power at the wheels and thus performance. However if power at the wheels was used to compare outputs it would be a lot more useful.
We also all have heard of dyno which are "more powerful" than other others, again this would go away.

Yes, MEK Motorsport, who do my mapping tend to produce more realistic figures.
They have tested a few cars which have been tuned on the big name "more powerful" dynos...MEK always measure a smaller number.
After sorting out the fuel pressure issue, it's been back for fine tuning...now producing 173bhp.
