You have decent data so lower the dV/dt to something like 0.3/0.25. Looking over the mean/mode data I would say that the 1st rescale was pretty good. I would revert to that, smooth it out (I've added the data below) and then use the Engine Load Comps to get the last bit dialed in as you'll get a finer tune as the last bit of variance is probably due to changing manifold pressures.
It's worth using the log view tab to give you a good overview of LTFT and STFT
