Hmmm 0.68 housing wheel spin for sure on the street looking at the graph part from that you wouldn't have the data for the rest of the graph, ie: IT, AT, Gear, Shoot_6f or Shoot_6. just a query as it clears any inconsistencies and makes the graph true to a point., plus i wouldn't be surprised if the 0.68 would be starting to choke that high.
Cheers
