Keith ,Mazda CX-7 2.2

Just a quick feed-back for you following the fitment of your Tunit module fitted to my Mazda CX7 last Monday. On the drive from home to your establishment I averaged @42 mpg. Following the installation, on the drive from you to my mothers home I averaged 52 mpg! On the 200 mile drive from my mothers to my home I averaged 52 mpg! No flook then!! As indicated on the day, the car does run much smoother and the pickup and throttle response are much better. Great job guys, I shall be towing with the car soon so shall let you know how that goes also. Many thanks, Keith.

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 :-)
