I wonder if the G37 community still has or still has similar issues. All I remember was the complaint about not using the ester oil causing throttle response problems with VVEL.
Although VVEL is neat-o and keeps the torque band flat I wouldn't mind switching to the VQ38HR from the 380RS. I never had throttle response issues with the 350Z other than the transmission killing the fun. Nowadays when I'm in the passenger seat of a 350Z, I'm usually pinned to the seat at low revs... something I miss
