Mike ,Renault Espace 2.2 DCI
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 :-)

2nd vehicle i have had tunit on and my range rover is a v6 but drives like a v8! Consumption improved from 25 to 30 miles per gallon. Already have recommended it.
