Up to 82hp to the wheels (100hp+- crank) on a completely stock car or MORE on a fully modified car!!!
With the insane turn out of the original N54 JB4, it was clear that BMS had to take it to a whole new level with BMW's new S55 engine. So for all you new S55 owners out there Burger Motorsports has finally come out with the infamous BMS S55 JB4 Tuner for the new single turbo engines that are in the F80 M3 and F82 M4.
From the factory all of these BMW's come very detuned, and far from its full potential. 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.
