Also what was the air fuel ratio like on the road on boost because as far as im aware cars run richer on the rollers than they do in normal driving conditions so therefore is it not a possibility that no det was present on the rolling road but on the motorway for instance the higher level of boost at 4500 rpm coupled with a leaner air fuel ratio det occurred ?
