This is a high-performance Stage 2 tuning file for the Ford Mustang GT 5.0L V8 (S550), equipped with the modern Bosch MG1CS019 ECU. This calibration is designed for enthusiast vehicles that have been physically modified with a high-flow or decat exhaust system, and where the OPF/GPF has been removed for track use.
This aggressive remap is engineered to extract the maximum performance from the naturally aspirated V8 engine. By extensively re-calibrating the ignition timing, fuel maps, and variable camshaft timing (Ti-VCT) to work with a free-flowing exhaust, this tune delivers a major increase in horsepower, torque, and throttle response. It also provides a much more aggressive and satisfying V8 exhaust note, perfect for the racetrack.
