I think the main trouble with measuring the pressure in the delivery line is that there doesn't seem to be anyway of comparing this measurement with the data in the FSM. The FSM is based on begin of delivery which happens during the power stroke. The maximum pressure measured in the delivery line would occur during the compression stroke...

...if anyone has got access to some official data or unofficial data then I for one would be interested in seeing it. (If it has already been posted in the many other threads please say which one 'cos I've missed it)
