Can not say much about the tune, other than it was done by BR Performance, one of the bigger tuning shops in Europe. They said, due to the exhaust, they were able to tune this 370Z further than any other NA 370Z. After two days, I got the car back along with these figures. Not bad for running on 98 octane, not even the 102 racing fuel stuff!
With the installation of the 4 valves, I can switch the exhaust from a quad resonated, dual catted and back muffler setup, which keeps my neighbours and local law enforcement happy, to basically straight pipe, which keeps me happy.
