BMS' entry level S55 tune safely boosts power and torque from 40-50whp with two easy to install & remove plug and play connections. This tune is equivalent to the S55 JB4 when run in "Stage1" mode. It's a single map install and enjoy tune that delivers smooth and reliable performance. Note the Stage1 DOES NOT have CANbus and thus does not include the datalogging, map switching, and other features found on our S55 JB4 tune. The Stage1 can not be upgraded to a JB4.

The BMS Tuner for the S55 is a piggy back system, which means it is untraceable by scan tools, so no need to stress about the BMS S55 Tuner voiding your warranty. The BMS S55 Tuner is simple, it plugs into the vehicle's computer and controls the amount of boost. Not only giving you unheard of horsepower and torque gains but also better throttle response and an overall better sports car feel. Whether your vehicle is stock or fully modified, the Tuner will adjust to the modification and make the most out of them. All this and more makes the BMS S55 Tuner the #1 software choice for the fastest 1 series and 3 series in the world. When it comes to choosing the best performance software for your 135i, 335i/xi, or 535i GT, only settle for the best with the BMS S55 Tuner.
