It's just over 3 weeks and 3,000km's since I had the car ('06 e90 320d) mapped by Martin. I'm absolutely delighted with the results. Massive improvement in power and completely removed any lag. Very happy with the service and Martin, a gentleman.

As for mpg, pre map I was running at around 44mpg on average and I'm down to about 42mpg now. There is a definite improvement in the mpg on long journeys so I'm losing through city driving. That's probably due to my all of a sudden heavier right foot :wink:

As I said to Martin on the day, I don't mind losing a few mpg's for the gain in power so I've absolutely no complaints with the result. No doubt, once the novelty of the extra power has dwindled and I start to drive like I always did, my mpg will probably return.
