Alright Chris, Just a quick email to let you know how pleased I am with the figures coming back for the average MPG after having the Tunit fitted. On a steady journey up to the NW coast of Cumbria: Without Tunit average 38.8MPG With Tunit average 47.2MPG All I can say is what an amazing bit of kit it is. Thanks

Well, its amazing! I could not believe that fitting this little box would be like fitting a brand new engine. Power went up, so acceleration improved. We have an Auto box, and the changes became smoother. Then the big bonus - 14% improvement in economy on the school run, over 20% when doing long distance motorway. Previously our Grand Espace was stuck on 25.7mpg. since fitting the Tunit we get on average 29.5mpg. On the motorway, with a long journey we see 34mpg (before we'd be lucky to get 27mpg). So all in all, it makes for a better drive, better economy and is like buying a totally different car. Dealer serviced it recently and not a mention was given about the Tunit :-)
