Reliable Remap Service in South Wales

Hi All,



I have bought a 08 Laguna 2.0dci estate and averaging around 42-45mpg.



I am thinking about getting an economy remap done and therefore looking for a reliable remap service in the south wales area (or near enough), preferably a tried out remap station with positive feedback. Could someone recommend one please?



Also with relating to the remap - I am going to travel across europe - now I read something that the remap will adjust the ECU to local conditions. Would this mean that I should not go for a remap as the car might not work properly when I am in Spain or Italy or Turkey?



Thanks for your help in advance,
