Stephen,Ford Mondeo TDCi 130 auto

I recently purchased a TUNIT for my Mondeo 130bhp Automatic station wagon. I noticed an improvement in performance, smoothness and fuel consumption immediately after fitting but it was not until I did the round trip to UK last week that I really saw the difference. I drove 3500Km in seven days my average consumption was 6.5l per 100 km, previous trips gave 7.2l per 100 km an improvement of 9.7%. The extra power available was particularly noticeable when climbing the quite steep hills on the French Auto route resulting in a much more relaxed journey. I would like to congratulate you on a very good product.

Jeremy Davies of Bernard Davies Commercials was very efficient at fitting the Tunit. I have just returned from a trip of around 800 miles. I have only checked the fuel consumption by means of the vehicle computer- not brimming the tank. This, however, shows an improvement in fuel consumption of marginally over 9%. The power/torque improvement is somewhat more difficult to quantify but on the only occasion I really booted it to try it out (not towing) it really seemed to be an improvement. When towing the torque is more obvious low down in the rev range. On main roads I seem to use around 1500-2250 revs an aweful lot. It is surprising how well I can hold top with no loss of roadspeed (measured by my Tomtom) on uphill inclines compared to previously. Also I can get into top gear much easier than previously and acceleration seems much improved. I hope this feedback is useful to you. Thanks again to you and Jeremy
