What size bore is the Buddy club?
I think mine is probably a bit less restrictive than yours
My car has been on 2 different dynos & pulled the same figures on both of them. Will see what figures I get in a few weeks when I get anothere dyno
For a P1? A few hours max.
Wessex in Cardiff had my car for 4hours doing a P1 (Apparantly none of the service ramps there can accommodate my car & they had to wait for the MOT ramp to become available )
Noise is normal, I get that sometimes
