on the golf gt tdi forums, there is a 800/900 and 1000 mpt (miles per tank) club...

I can get nearly 60mpg on a good run in my unmodded 110 gt tdi, but a chap at work has just had his gt tdi 130 remapped and says he gets 60mpg even when doing 90/100 down the motorway..

For the people getting 800+ to a tank, they need be averaging 80+mpg

Does a remap make that much difference?
