The remap will vary depending on who did the tuning, there is an awful lot of rubbish out there, unless you are going to the likes of AMD you run the risk of getting a rubbish file on your car. Do not think that a big name means you get a good file for your car, I used a local company who really knew their stuff, how much to add, what maps to change and by how much, not like the larger companies that just reuse files and only change a few of the maps in the ecu, the difference was massive, my car was very smooth even when driven slowly, I got an extra 10 mpg on the motorway and loads more power and it did not cost what the large well known companies where charging, I have had lots of cars remapped and have used different companies in the past, eventually I stuck with AMD as their work was miles better than any other company, the local company I used last time was just as good as AMD remaps I have had in the past and was 1/2 the price.
