RCZ I emailed you the dyno chart, you will see the gains were across the entire power band.
I think as expected the headers don't do much, they didn't in the 350Z either, but after running with them you should pick up some more.
Also I think once we get Uprev to gets us the 370Z maps we will pick up some nice gains from tuning it, the car is running rather rich around 12.5 plus we can add some timing
