I mapped my first 335d (DMS Automotive) here in the Uk and never had any issues at all over 25,000 miles. The figures were 345bhp and 535lbft. I have just had the same map on my new 335d!!!! They are awesome with this done, torque is amazing and there are not many cars that can live with them day to day, in fact I havent found anything that can beat it yet.
