There is a video showing what the gauge does here (FIDC link installed)...

That is a second gear pull WOT to fuel cut at 8000rpm. Sorry about the
camera being upside down but I had to attach it to the handbrake and
couldn't get it properly lined up. You can see the lights OK though
Here is the data from my log of the run.
RPM vs
IDC vs

5000...42.6...28
5500...49.8...39

7000...68.6...44
