This ECU upgrade is tuned around midrange power, not just top end like some of the others. It gives excellent gains (10-15hp) and really makes your BMW come alive.
We have been performance tuning cars for almost 10 years, with some huge success. Our chips are in 1000's of cars world wide. These are not Japanese copies that require 100+ octane, but tuned and tested in local conditions.
525 525i 325ia Motronic 3.1 Installation instructions available.
