I recently bought a 2004 325Ci with the SMG. I've already put a cold air intake and a Remus cat-back exhaust in. What are some recommendations on what to do next, performance wise? Money IS an issue...so supercharging it really isn't a possibility. I've thought about a chip or programmer...or some ignition system enhancements in addition to wires and plugs and whatnot. Thoughts?
