COBB's 3-port configuration replaces the factory solenoid to increase control authority over the wastegate, helping deliver steadier boost across gears and conditions. It is suitable for stock or upgraded turbos when properly calibrated. An ECU tune is required after installation to achieve correct boost targets and safe operation.
