Theres a few good places around the country try a bmw forum for recommendations or a bit of googling , but new turbo diesels respond sooooo well to a decent remap always surprises me how quick they are compared to the older style diesels.
Reason modern dervs respond so well to a remap, is as they are, in essence, restricted from the factory.
The reason being is powerful 'Nox' emissions, by advancing the injection timing you make far more efficient use of a given amount of fuel, thus a win win situation in terms of power and economy, BUT not good from a emissions perspective.
I always wonder how it works in relation to an MOT, as you now have harmful pollutants being emitted?
