Read some of your old messages, hard to believe you've invested $30K in your BMW. Following your previous advise, I am currently upgrading mine with some Dinan Stage 2 (engine software, transmission chip, cold air intake & 3.15 gear). The first three items are in, slightly quicker response, better daily drivability. Waiting for the 3.15 gear. Anyways, thanks for playing a pivotal role in helping to keep this board informative & easy on the eyes (from reading nasty emails).
