2014 Bmw 520d tourer

I left a review on another web site but since I’ve done it I can’t see it anywhere. So I’ll leave one here. Have to say a friend around the corner was having it done as I came home from work. I was looking at getting a remap so stopped and asked. Explained I had a horrible pull away power curve and delay on this 2014 Bmw 520d in my eyes it’s dangerous pulling out of turnings / round abouts etc. The guys Marco and Jemma were very helpful and explained what they will do and how the car will be there after. It was Jemma that remapped the motor. The motor came out exactly to what they said the horrible power curve and delay was gone. Brilliant. They also told me before they did it if I wasn’t happy with the remap it’s a 30 money back guarantee and they would reinstall the original map back in. You can’t go wrong with that, with door to door service is a no brainer I will definitely use these guys again. Highly recommend them to anyone, friendly explain and answer any questions asked.
