Final drives and onboard calibrations

If you were to install an aftermarket final drive in your car, say a 4.5, what onboard measurements, if any would be thrown of? Milage? Gas milage? Anything? It seems to me that when we change the relationship between driveshaft revolutions as related to the revolutions of the wheels something will be amiss. Or am I not understanding something?
