I just installed my BMS Tune this weekend...wow! There is a noticeable increase in power and torque. Before I installed it, I did a few 0-60 test runs with a stopwatch as a point of reference. Best time I got before the install was 5.7 seconds. After the install, on the same road, time was 4.9 seconds. My car is a 2012 328i with manual transmission. Install took a little longer than I expected. The first plug, under the engine cover, was a pain to get to, but after that the rest of the install was simple.
