True, you can add a switch to the unit for map switching, but a properly tuned vehicle should already be configured for both maximum fuel efficiency and power. You control how much fuel is expended with the throttle pedal, not the tune. A map switching switch is better used for switching between two completely different configurations (i.e. C16 and pump gas).
