The BMS tune definitely adds more power, does not trigger warranty codes due to the MAF manipulation connector, and will be upgradable to their stronger Stage2 tune that has in dash features, map switching, code read/delete, etc. Not to mention it costs less. You made the right choice.
I just installed it.No power increases
. I still do 0 -60 in 5.8 to 6.2 seconds.
I have a 328i sedan 2013 automatic. I just emailed john and sent him pictures on how i set it up i will be waiting for him to reply.
i turn off DSC, put the transimission in DS mode, and just floor the gas pedal.
Am i doing it wrong ? is there a faster way to accelerate?
