I have the BMS Stage 1 on my 2016 320I which is the unit used for the dyno testing. I have it set at +4 psi and it made a huge difference. According to the dyno results, it should put you at about 220hp.
Plus it only brings the total psi up to about 12psi which makes me believe that there will be minimal impact on the car's reliability.
