Take it from someone that has the tune from BMS that Mike mentioned right now, that my gas mileage has not been impacted, and to the contrary, I've seen an improvement (considering the way I've been driving with the tune, my gas mileage hasn't suffered).

There are 2 other companies that have tunes available: DTUK (2) and VAC (1).

If you're going to toss up a tune for a car, at least make sure it's for the US Spec d, rather than the explicitly stated 286HP (EU) version of the car:

Application intended for: BMW E90 E91 E92 E60 E61 E70 E71 335d 535d X5 X6 X-Drive35d 286hp version from 2006 2007 2008 2009
