Australia 9th Jul 11 Dear Andrew, First of all I would like to thank you for sending me your DTUK Diesel Tuning System. By following your clear instructions it took 15min to install into my car which I have been now driving for 5 weeks. I must admit, I was a little bit sceptical as to whether the system would improve the fuel consumption and the power of my car, however, your description of the unit has been 100% validated and the system is FANTASTIC. After the first test drive I could feel a dramatic improvement in my car. Even my wife, who never takes notice of things related to the car, noticed a difference. The fuel consumption of my Peugeot 407 Diesel dropped from 8.5L/km to 6.8L/km which is an amazing result. It was my best investment in my car for such an insignificant amount of money. I’ve already promoted your unit amongst my friends. Once again, thank you Kind regards Marek
