Lots of missing details, otherwise the MPGs are out of context
Gassers are designed for stoichiometric ratio during open loop and when up to temp, closed loop can vary +/- depending on both temp and whether oxygenators are in the fuel
What is the elevation ?

What is the throttle position ?
What are the gear ratios from the tranny to the diff and to pavement vs ICE RPMs at the pavement
