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.

Can now leave in gear on lower revs and reduce number of gear changes, also pulling smoothly throughout rev range ? Just need to fit new tyres on the front wheels to further improve mpg! Improved to 64.8mpg ? 16.5% better.
