I've been trolling around is300.net for months now, haven't seen any decent power mods except for the various turbo kits. What would you recommend?I mean less serious modifications. I/H/E & AFC tuning gets about 25-30rwhp on the IS. I bet you get about 5-8 hp on a BMW, which just means that BMW designs/tunes their engines very well. If you want any kind of forced induction, I don't know as much, although Dinan charges a permium for their work/products.
