My X5 M50D was probably the best car I have ever driven. I have remapped every diesel I have owned. I decided to use Viezu for the current car and organised by phone to go to them to have the work done.
The H.Power and torque were very good before the remap. After the work was carried out the Horse power had increased by about 60bhp and the torque was way higher than I ever thought possible.
The car now performs better than the 5litre Jaguar I used to own. I have in the last 7 days found the fuel consumption has gone up by about 10% and and performance has increased by an amazing amount.
I have told my BMW dealer it has been remapped and both managers have driven the car and were really impressed.
I would recommend Viezu to any owner who wants to get the best performance from there car.
Many thanks for an excellent job!
