TD6 with Van Aaken Smart Box.

Bought a Van aaken tuning box off E Bay. Was still wrapped inside box unused. I have had it in the car for about 2 month but my mpg has gone down not up. I do not drive like a GTI. My mpg went from 21.4 which would go up a bit on a run down to 21 regardless of how I seem to drive. I thought there were diffrent settings on these boxes but I cannot see any. Any ideas any one??

Found out how to adjust. Now on middle setting rather than lowest as set when supplied. Feels faster but have to wait and see for mpg.
