Every car is different, but we usually see anywhere from 12-22whp from dyno tuning the 370Z. It depends on the condition of the OEM ECU calibration that you walk in with, and how it's been adapting and responding to the mods on the car. For instance, if you are running extremely rich or extremely lean, the power gains we'll make will be extraordinary. If your walk in OEM calibration is closer to optimum, than I would expect a gain on the lower end of the scale.
I've seen a few NA cars come in with lots of mods, and AF ratios in the 14's at WOT! Talk about poor power, and high danger!
