I'm new to this site. I have a E30 325 Cabby myself, but my girlfriend bought herself a '04 e46 316 four door at the weekend. I presumed it had a 1.6 engine, but it has a 1.8 engine. only problem is it feels like its a 1.6 or else down on power. Just wondering if there is anything that can be done to tune it up considerably.
