Do you have the powrtuner or who is tuning it, what programs are you using for tuning? I don't see any 02's get past 900 on the narrowband in that scan but your also not entering PE that much. You must have PE afr at 11.5 or so? I would try adding 10% on the maf table from 6000 on up and smooth that out. Wait til the fuel trims settle back down and then post a scan again. See if a larger change in the fueling will alter the kr any. What is your PE enable tps at? Here is what mine is set at, but you can probably go a tad higher since your s/c.
Fuel -> PE -> PE Enable TPS
