No man I think you are missing the point. As far as electric systems is concerned I am clueless, but when in comes to performance parts,and dyno results, not just what people think their hp is but what is it really, cold air, headers, cat back exhaust. It is proven that you can get gains of anywhere from 13-18hp. It a proven fact on your car.
