I remapped it as well after a flawless warranty period expired. From the stock N13 130kw (120i model 2015) and got 170kw at 6300rpm in a faily linear fashion. Very happy with it indeed since then.
The lower band remains the same with stock 250Nm (up to 2500rpm),then the new map comes in linearly to 3500 reaching 310Nm max torque, up to the limiter.
This allows a normal use with stock map a less component stress in the daily driving, and a very controlled via rpm power delivery in the spirited driving.
The fuel efficiency remains the same as stock or slightly better considering the power gain.
The car performance now with 6kg/HP and the handling is just fantastic.
