My 2004 BMW 320d with over 70000 miles on the clock recently gave me over 700 miles from a single tankful of fuel. And I wasn't driving slowly!

I have had my unit installed for some months, at first I had problems with fuel consumption! higher than without the unit in. I phoned your experts and was advised to take the unit from a setting of 3 to max(9). I was also told that your operative believed that torque was the secret for performance and lower fuel consumption. I can now after extensive use of my car towing (a 24foot van) tell you he was spot on! I use the torque where it applies to my outfit, I can tow comfortably at 53mph at 1600rpm, the available torque allows for a down change if needed for hill climbing, fuel consumption 33-36 mpg over the whole journey. Be fair! at 1600rpm the engine is just ticking over. Now I can also tow the same van at 70mph, now I am using the extra power supplied by the unit, don't look for fuel savings here as I will return 25-27mpg. A word to the wise don't expect to see any use from your unit if you use Supermaket fuel, its crap, Some time ago I stopped using Tesco and like fuels, and I now have a different performing car. Sorry to go on, but thought you would like to know. Regards Denis Hall.
