I had oscillation issues with my stage 2 Dinan tune. After I stacked a JB4 G5 ISO on top, the issue went away. All the pluses of the Dinan tune(which isn't a whole bunch) and JB4 goodness.
Now before a flame war starts, I would imagine that stacking any of the other tunes/piggy backs on top would net the same results.
