when we ordered our 2019 P4 BHM lent us a new P4 to go to lunch in. We felt that it felt flat and needed to be worked to enjoy it. Keith promised that our new one, with full flow exhaust and remap would be different. There was some confusion in the end as to whether the factory remapped it but I can tell you that it had bags of low down torque and absolutely flew. I think it as quick as our Roadster, certainly up to legal speeds, the difference of course is in the way it delivers. Jamie at BHM used to take it home with him ( we had asked BHM to put some miles on it ) before we could pick it up and was impressed.
