i have stacked them. in all honesty it's better with just the edge. i only have the bully dog to adjust top speed and for tire size (future). the problem with stacking them is that both are advancing the timing a fair bit. i think the bully dog even more so (a lot of timing rattle). so the only safe way to run them is with the juice on stock timing. BUT, that reduces the output quite a bit. i find that my rig runs faster, smoother, and little if any timing rattle with just the juice.
