Mine is KO3s/dbw and i've been on many rolling roads, somedays mine makes 220/247 other days I,ve had it a low as 195/217
. Interpro gave me my highest figure and westec my lowest. Jabba are known for having a complimentry road I believe too. 
Good point, but was the ambient temperature roughly the same on each day, as this can make a huge difference?
Anyway, as long as we're all happy with the cars on the road, hey???!!!
