I think I want to still hold over 530bhp so if we need to cap it at 2.2 to keep that through the rev range then maybe that is the way to go...possibly easier to sell 2.2 as well. I like the ideas of 580bhp on 7670 but want max torque as low as we can and throttle response so the turbo will be the driver as to spec as we won't have room for more and don't want lag.
