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

Hi Daniel, since the fitment of the Tunit V-CR unit to my new Citroen C5 I have noticed a marked increase in fuel economy, performance and refinement. At a steady motorway cruise the average consumption has improved from 40mpg to in excess of 50mpg. Performance has also increased and the added midrange torque makes overtaking swifter and safer. I am delighted with the result, especially as I fitted the Tunnit to enhance performance rather than economy. The added benefit of being able to transfer the tunit to another vehicle in the future is the icing on the cake.
