Description
Unleash hidden power from your Mercedes-Benz turbo engine with the Burger Tuning JB4 Tuner. This plug-and-play upgrade delivers up to 50WHP on the C300, 60WHP on C400/C450, and 70WHP on the C43 AMG—with even more potential on race fuel or E85 blends.
The JB4 connects directly to easy-to-access engine sensors and your vehicle’s CANbus OBDII system, enabling advanced boost control, smooth power delivery, and additional safety features no basic 2-channel tuner can match. Installation is quick, completely reversible, and compatible with both AWD and RWD models.
Whether you’re looking to cut 0–60 times, improve ¼ mile performance, or simply enjoy a sharper throttle response, the JB4 transforms your Mercedes into the performance machine it was meant to be—all without an ECU flash.
