    Just curious if anyone else has noticed that using the Ultra-Gauge they really got their MPG's up? I calibrated about a week ago to the new tire size using the recommended procedure of going on a major highway with mile markers, driving a certain distance and then telling the gauge how far you went. To make sure it was as accurate as possible, I drove seven miles (figuring that if I did it for only one mile it's possible the mile markers could be a little off). Now, just by watching my driving habits, I'm averaging 23.5 mpgs! Anyone else seeing this? Hoping that's accurate cause that means I should be around 25 mpgs in the summer. Never woulda expected that with a 4x4, even a 4 cyl.

    u will hit that with a 4cly. I have not noticed any change in my MPG. i have always tracked it on excel. calibrated the UG which reads about 0.5mpg more than my spreadsheet does. I tend to believe my sheet over UG, as it has not changed since installing the UG. it is nice to see how well my CAI works.

    Make sure you do the Ultra Guage Fuel Calibration after calibrating your tires.

    I looked through the manual, i found out how to calibrate distance but I can't find out how to calibrate my tire size.

    My UG and manual calculations based off the truck trip computer have never lined up (UG reads high). Then again my UG pegs my speed at about 1-3 mph below what the speedo says depending on my speed (less difference at higher speeds). That's on stock size aftermarket tires too.

    That's the nature of MPG readings ... a whole lot is dependent on the calibration of your instruments. Perhaps the only way of calculating an accurate MPG would be to use a GPS to track miles.

    Yeah that's true. Paying attention to the realtime MPG gets me to lighten the foot. The overall MPG of the UG has always been a secondary thing to me. What matters to me is the tank-by-tank calculation, and how much it goes up or down relative to previous tanks. That's why I will always calculate manually.

    What I did is zero out all my trip meters and then drove about 20 miles according to my GPS then put that number into the calibration field of the UG.

    For giggles I multiplied the trip meter distance by the relative circumference percentage of the original 31s (265/75/16s) to my present 33s (285/70/17s) which was roughly 1.4. That number was actually a little less than what my GPS actually showed. Either way, my Avg MPG is a pathetic ~14.4.

    When I calibrated the distance, I used both a 5 mile trip and my GPS.
    they were both with in 5 ft of each other. So I believe both ways would accurate.
