I'm not sure if this might be the case but you might not be seeing knock correction for that light throttle jolt because the knock correction tables are usually at 0 around that light of a load and low rpm value. What you can do is increase those 0s to 2 or 3 degrees and log the results, if you see that it is pulling timing in the area where it is hesitating, you will need to decrease the base map iginition advance. I had this happen in MY04 and finally I took a look at the base map on light load columns and found that there was way too much advance in one cell. Lowered it and it fixed the hesitation.
