Ok folks, just done over 1000 miles and I have tried all the D mode settings and I cant see any difference in fuel economy! All the D mode seems to do is alter throttle response, I thought it may alter the ECU and alter performance the same as moding the chip can alter performance or fuel economy.
The best I can get off of my manual 1.6 Dig T is 30.9 mpg!
What is any one else getting??
