Not seeing a big change with the speedometer adjustment. The dash reads higher than the GPS app no matter if I set it for -2.5% or +2.5% and I don't notice a definitive change between the extremes. I'm leaving it at -2.5% for now.
Next step is to replace the rims/tires to get better efficiency (lighter rims, lighter tires, lower RR tires) and somewhat correct the speedometer with the change in RPM (revs per mile).
