but you have to remember that the cooper works was tested at BMW, and so takes from those wierd high-altitude german figures. On a rolling road, I'd expect the works conversion to put out the most. On a track, I'd expect the works conversion to p*ss all over a superchip. On a bank balance, well, it's hardly a works conversion is it
It comes down to whatever floats your boat...
anyway, this is slightly off the beaten track!!
