"dead nuts put of the box" = ??? Not sure what that means.
I set the gas tank to 10 gallons and engine size. Then I drive and I get mpg numbers. At the end of the tank of gas you can adjust how many gallons were used to make the mpg number more accurate. This can vary from car to car with different transmissions.
My overall numbers are very high and optimistic by scan gauge II if I do not adjust for error. My true mpg is about 25 to 29 and my non adjusted scan gauge mpg is about 35.
Also many times I notice that the readout for instant mpg is stuck at 9999 even with changes in throttle position. I could leave it there stuck and go along or blip the throttle to get it to wake up. Usually after a bit of time it wakes up without effort. Also in coasting mode the numbers are quite optimistic and never seem to even out compared to the lower numbers I get in heavy traffic. I have noticed if you do mixed driving with a little urban use the overall average isn't very good. To get high mpg you really need to avoid any heavy traffic and spend most of the time on the highway in less congested areas and at constant speed.
For daily driving I mostly get about 26 mpg and the only way I can get 32 mpg is to take one long trip on sunday in light traffic. So the capability is there but for daily use under my normal conditions I rarely ever see more than about 28 mpg even with the help of scan gauge which is pretty sad considering my 2006 Honda Civic sedan with AT gets 32 without a fuss.
