I've found I'm not a sensitive enough driver to detect a 5% change. I've tried 45/55 55/45 a bunch of times and I'm personally convinced it does nothingThat is good information - My theory is thinking I can reduce a little on power understeer in certain turns with 45/55 but I probably still need to clean up my driving a little to reduce under steer. How about regen settings? I have found more speed by reducing mine a little.
When I drive AutoX, It's either on power or full brakes, but that's just my style. I run 2500+ wh per mile in my runs (about 30 miles total range), so I can't imagine regen is doing much of anything, and thus I've never considered it. But it's interesting and I'll have to try it next time.
