Rockstar:
Congratulations to your Purchase.
Be sure to post in our QX4 section also.Your have a pretty new vehicle, but JWT may offer a chip for you sooner or later.
If not soon enough you can always go with a standalone ECU.
As for extra power, since your vehicle has the VQ35DE, all mods that fit that car will also fit yours.
And a twin Turbo set-up for the VQ35DE is around the corner from a couple of tuners.Or if you can't wait and money truly is no object, you can always have a supercharger custom built.
Fred..
PS: I may move your post into our QX4 section.
