Incorrect.

Although the 458 has a remarkable engine and certainly s VE over 100%, it is not uncommon for a moderate to highly tuned production engine to also do so. I don't have the data handy, but am highly confident the current M3 does. It is a remarkable breather. One fellow posted here about his own lightly customized B MW (Z4 IIRC) intake and airbox mods that got him up to around and I think over 110% VE. He even built his own simple but accurate test system.
