Ive searched cant really find an answer to this. Looking to get remap done on 1.8t 150 avj Quattro. Hopefully to see an mpg improvement on the motorway, around town its not really an issue. And also the power gains. Currently averaging around 380-400miles per tank on motorway (I drive a 500mile commute on the motorway) Wondering if i can get an improvement on this to maybe 450miles per tank.
