Performance Software

Performance Software

CarBahn’s performance software is designed to deliver reliable “Smooth Power” meaning the software is calibrated correctly by using a safe approach to power adjustment. Excessive torque will break the tires loose, overload the engine and ruin the drivetrain. To reach optimum power, the software is easily combined with our high-performance intercoolers/heat exchangers and turbos. Call (650) 495-0421 or Learn More >
