Anyone with a mate who got one or has one themselves or indeed the Touraeg with the same engine (unlikely here lol) here's some real life feedback from a recent customer of mine
He's just been on holiday and compared to the same trip he took last year, the remap SAVED him £30 in diesel AND he travelled more miles

Fully laden with kit and his family he was seeing 34mpg on the trip computer compared to the 25mpg he was getting!
Its got milk bottle tops for brakes though
