I didnt read that acticle but im assuming from what you guys are saying its an article on grounding the electrical systems, or the muffler, or the cat. You can make fun of this but in some cars this actually DOES work. Im not sure about BMWs but cars like VW golfs and DSMs have very weak and sometimes faulty grounding. This effects the cat and the o2 sensors and various schenanigans and does effect output, not so much of horsepower but of fuel efficiency, so you can kinda say your hp went up because your gas useage goes down... if you get what im saying...
