You see, at 2760rpm load doesn't rise as fast with throttle opening as it does near idle..
Again, this is a common misunderstanding. The fact is that the throttle plate has a lot less to do with VE that people intuitively think. See my previous post #129.

In the meantime, no one has to 'assume' any more. I've calculated the VE of this engine in these conditions.

Volumetric Efficiency calculator
Note that this calculator shows the Aveo's VE to be 79.999%
Givens: CFM=62.37, CID=97.64, RPM=2760
