Description
Unlock significantly greater performance from your BMW G8X M3 or M4 with CarBahn Performance 724 HP Stage 1 ECU Software. Designed for S58-powered automatic transmission models, this ECU calibration increases horsepower and torque while utilizing CarBahn EVO Intelligent software to adapt seamlessly to different fuel octane levels.
The Stage 1 calibration delivers up to 702 HP and 650 lb-ft of torque on 93-octane fuel and up to 724 HP and 655 lb-ft of torque on 100-octane fuel, depending on drivetrain configuration. The software also removes the factory top-speed governor while retaining existing factory safety features and adding additional protection as needed.
For optimal performance, CarBahn recommends using the CarBahn heat exchanger, part number CBG8X-2001, or purchasing Power Package 1.
