Tunit arrived in good time and was very easy to fit, the small picture helped a treat! On the first outing, with the dial still set at 5, the Jeeps MPG reading steadily rose and kept rising for about 150 miles or so giving me about 5 miles per gallon extra. With the dial set on at a lower number, would the fuel consumption increase further? The 0-60 time is not of huge importance to me as the jeep is fairly quick for its size anyway! Regards and thanks for your help again
