The performance gains are neglegable really. I gained about 3-4 hp on the dyno after the install of my HKS circle earth. What it does do is provide a much better ground for the ECU and other components of the car to use. This in conjunction with a well tuned car will get you the most out of your car. If you have a stocker I would say save your money...
