Mike at BPM is the s*#t! I've had the e90 M3 tune from BPM and that was nuts, the X5M now drives like it should. BPM has the best all around tune IMO because it not only livens up the truck, but it's safe on it. You don't have to worry about blowing up your engine because the safeguards are still in place to prevent stupidity causing engine damage.
