Most of my driving is inner city traffic and I'd say around 320k's per tank....just can't cruise though, love the noise too much and the tempting acceleration....but that's why we buy these isn't it???

Does any form of tuning actually increase economy as well as performance? I know it can in certain cars but not sure about M3's.
