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

I have had a tunit unit fitted to my VW Passat estate now for about 7 months, and it's great. Performance and fuel economy as well. What more could you ask for. Well Done Tunit, and Best Wishes for the new Year. I hope your sales of tunit units rocket so fast that you can't keep up with demand.

Happy Christmas to all.
