This is a high-performance Stage 2 tuning file for the BMW M4 Competition (F82), powered by the S55B30 twin-turbo engine and managed by a Bosch MEVD17.2.G ECU. This calibration is designed exclusively for vehicles that have been mechanically upgraded with high-flow or decat downpipes to achieve maximum performance.
This aggressive remap is engineered to transform your M4 into an absolute monster. By completely recalibrating the boost, fueling, and ignition maps to work with a free-flowing exhaust, this tune delivers a massive increase in horsepower and torque. Expect ferocious acceleration, razor-sharp throttle response, and a much more aggressive exhaust note with exhilarating overrun burbles, perfect for the track and the most demanding drivers.
