26th Nov 09 Hi Andrew Firstly, thanks for quick despatch of order which arrived the following day and then your advice on fitting and set-up. In the end it was easy to fit and took about 15 minutes, the hardest part of which was trying to unclip the plug to the common rail which is tricky to get to. Since deciding on a setting I have only had the chance to try on my normal commute to work (a 25 mile round trip) where I was getting around 39mpg before fitting the ECO3 unit. Since fitting the box and a K&N panel filter, the power delivery is noticeably improved with more urgency lower in the rev range. It is rare that I need to use more than 3000rpm in normal driving. Overtaking from 30-50mph is effortless and it is in this range where you really appreciate the extra power as you don’t need to change down and rev the engine to get the performance. On top of that, I have still seen 44mpg on each of my last 3 trips to the pumpsthe only accurate measure of fuel economy. So in summary, noticeable improvement in power, torque and a 5mpg improvement in economy so far. The only downside? It is tempting to use the extra performance and drive a bit more enthusiastically! Many thanks and best regards. Carl
