I'm assuming you did a carb tweak or something to improve low end torque at the expense of some low end HP? Hard to tell with the color resolution of the actual graphs (order of the runs). If it were me, the Torque ramp starting at 2200 is where I would have left things - the tune I would be looking for.

Carb tweaks and linkage adjustments...
I running twin Quick Fuel 750s on a tunnel wedge. I also think the go-fast pedal got mashed at different RPMs and the vacuum secondaries took a moment to open all the way. The larger CFM carbs causes the secondaries to be a bit more sluggish than, say twin 600s.
