Doesn't sound too bad then economy wise then!
To be honest I find it hard to waste fuel in my tdi. I can thrash it up in the mountain roads and I still seem to get atleast 40 - 45mpg!!! I love diesels
Well, apart from the lack of immediate power. I find if not at the right revs, the turbo lag is awful and I just go nowhere which is a bit embarrasing at times! lol.
But when the turbo kicks in and all those torquey torques are let lose...
Apparently the remap will give more of a petrol like immediete power delivery

Also gives power further into the rev range which means less gear change when over-taking
