Which system of measurement Jac, by that is it as done by the world motorsport bodies where it is a set distance from the racing line under full power etc or is it by the method used by the various transport authorities around the world where it is measured at a set rpm at a certain distance from the tailpipe as there is one hellave difference in the outcome. A car at the limit on the transport authorities test system would probably hardly raise an indication on the motorsport system.
