I have a automatic 323i and i want to add some horsepower to it, but i dont want anything that will make it loud like an exhaust or intake. Does anyone know a computer chip or anything else that will give me more power?
shark for $300? I thought it leveled off at $350...
keep in mind though, the shark injector software works best when combined with an aftermarket intake. if you're worried about the sound, intakes don't really change the car that much. exhausts are the ones that make the car louder.
