The engine revs fine in neutral.

The chart starts at 2500 and the car was not wot untill about 2650. What your seeing is just going from a cruise to wot. It cruises at about 13.3 then when it goes wot there is a quick blip up to 14 (that is just a delay till the pump shot kicks in) Then it goes very rich due to it having to much pump shot and then levels out at about 11 afr and slowly rises till it gets to about 12.8 at around 5500.
