You either need an engine management chip (such as the Cobb AccessPort, which is being released for NA models sometimes soon) or you need to learn to tune the car yourself, with help from www.romraider.com. Get a Tactrix or VAG COM cable to connect to the car's OBDII port, and everything else is free, you just need to download the programs and study up enough so you know what you are doing. WARNING: you take the risk of blowing your engine to pieces by messing up your car's stock tune. Make sure you know what your actions are doing to the motor before you dig in.
