Does anyone know of any software upgrades for an E92 328i with x-drive?

The most commonly used tune is Active Autowerke's tune, their thread is on the second page if you want to take a look, I'd link you but I'm on my iPhone! I have been reading on this flash for a while now and I have yet to see a negative response. It is a little pricey ($500) but I haven't seen one person regret it. I have not looked into other tunes much but majority have not performed as well and I have seen some switch over.

I was looking through some threads and this one had to do with AA tune, and peoples reactions to it! (and the guy below)

I happen to be one of the lucky ones that lives less than an hour to their shop in Miami, Florida USA. I just did the Active Autowerke stage 2 93 octane tune with charcoal filter delete with high flow filter and their signiture exhaust. you'd be suprised what 20-25 smooth hp makes in the 328i. Talk to Andrew, he'll hook you up.
