Logged 3 WOT pulls, and now have another very lean area that I didn't have before, in the 2k RPMs. That may be due to compensations but it has me concerned that it's going that lean. The first two pulls show the lean 4k area. The third pull looks good in that area.

I'm new to tuning this platform, I thought I understood compensations and how at least fueling is getting calculated, but I can't find what would be causing these spots to vary so much in AFR. Anywhere to start looking would be a great help.

If it helps, I started with the OTS tune from OFT that I had been running on this car, and modified that. All I've modified is a little MAF scaling, and OL fueling targets. I rescaled my maps for boost and pulled about 6* of timing at full boost and ~10* or so for the next load column dependent upon RPM. These pulls were taken after starting and driving the car about 5-6 times for about 1-1.5 hours driving total. Maybe 40-50 miles though.
