Perhaps I am reading this all wrong? (and I have no axe to grind with anyone regarding maps etc)

The graph you posted Jamie, suggests a max torque around the 2200 rpm mark, at that RPM in 5th in my auto (without lock up), it is around 70 mph if I recall. I imagine that a manual would be similar RPM. To me, this would be placing maximum torque on the clutch for sustained periods? for motorway driving at least and it wouldnt be required at this point either, as you would be cruising (or at least should be lol). Or do I misunderstand dyno runs?

If I am correct, would it not be more useful to have the maximum torque slightly lower down the rev range for reliability, allowing it to be 'switched off' when an upshift took place? Therefore containing its power to shorter use.
