The car does rev longer but I think they were letting off before they got there as it was past peak power.
I actually think the shape of the torque curve is about right and if the graph was stretched across the whole page it would look like a really nice progressive powerband which is what it feels like to drive.
The graph is wrong because it makes nowhere near the torque it makes on the road (there's 50lb/ft missing) and the maths is wrong, pick any point in the rev range and the torque there and do the maths back to work out the bhp and it will be wrong, by several bhp on the ones i did.
Also the relative humidity is almost certainly wrong as it was a humid day and just starting to rain and im not entirely confident with the barometric pressure either.
