Mine was stuck at 12.8MPGs I reset as instructed and on hwy it says 21MPGs.
Im running 285/75/r16 but Jody adjusted my DP-Tuner for that size tire when I ordered it.
you have to understand that is not what you are actually getting. that is an instant reading. hand calculate it if you want an accurate reading, and dont ever rely on what the lie-o-meter says.
