Default Split STFTs only in a certain RPM range?

I'm running in SD with DFCO and PE mode off. I seem to be getting a pretty bad split in the STFTs (diff of 15) but only between 2000-2400 rpm and when tps = 0. It seems most of my log shows a small split (less than 5) when tps = 0 but it largest in this rpm range...then as tps increases the split goes away.

What might cause the split?

Misfire...?
Air leak only during that range...?
