I think it would be good to have a couple base maps without VVEL. I'm expecting the gains will be in the 3% range, similar to the G37. I'm sure the midrange and responsiveness of the car would improve as well.
That said, COBB should still have cracking VVEL as a high priority since it is a technology that Nissan/Infiniti will continue to use for many years and it could net some huge tuning gains (not to mention a ton of sales for COBB).
