J,VW Golf 1.9 TDI

Just thought I would let you know how the tuning is going on my Golf. I usually use nigh on half a tank to get to my parents.I arrived,and found Id used a fraction under a QUARTER of a tank,averaging 60mpg! Thanks for all your help.

colin,Toyota Rav 4 2.0 D-4D

Have been running Rav on setting number 8 for a while and fuel consumption on average about 5% better than standard but because the engine responds better I do tend to drive quicker than I should so don't save as much as I probably could. Torque much better because I can drive in higher gears at lower speeds than standard set up. Tows 2008 Swift Challenger 480 really easily without too much gear changing. Have recently moved the control to number 9 and so far seems to have improved performance and torque even more. I was talking to fellow tower with standard Rav 2.0 D4D and he was saying he was disappointed that he had to keep changing gear when towing due to lack of torque. I did give him your phone number. Very pleased with the system in general. Easy to fit except for the silly place Toyota put the fuel rail connector plug.
