Here is the email I got which is a bit more specific for you guys.

It's something we'd like to do, but the reality is that no one wants to assume the liability. It's not like a typical motor set up where if you break a valve, or a rocker arm wears you just go buy that part and rebuild.
The VVEL is only available from Nissan. Nissan will only sell the matched pair of heads as a complete unit. Approximate cost is $10k, thats just the heads, no other parts.
From what we see on the earlier motors the cam phasing alone is just about perfect from the factory. You can adjust them all day and you gain 1-2hp. With the VVEL we have no less of an expectation. So realistically no one is moving forward on the development of the software because the potential gains will be very small, and the liability is huge. Also there are exactly ZERO hardware pieces in development in the aftermarket. So no replacement pieces or items that would require a change in the tuning itself.
If these factors change we'll push forward with VVEL tuning, as with everything else in the Nissan tuning market we'll be the people that develop the technology and the other manufacturers will simply copy our work.
