seems about right for gas mileage.... with my stock ECU and A and R baffle kit I'd get around 80-90 miles till the light came on and then put in around 2.5 gallons.
After reading another gas mileage thread a while back and seeing peeps run out of gas within 10 min of getting the light I decide not to F with fate. Soon as that light comes on, I'm looking for a gas station.
With my newly installed Microtech ECU and K&N air filter I got a bit less gas mileage out of my last tank but about 50% of the time I was in stop and go traffic for about 2.5hrs so I'm guessing that added to it since the new mapping has my bike idling a little higher than stock.
basic idea here is get gas when that light comes on..... pushing 400lbs any distance sux....
