I noticed the same drastic consumption - I'm thinking of posting some logs at n54tech.com and having those guys tell me if anything looks off. Perhaps you should consider the same.

If your foot is in it fuel economy is going to suffer a lot. However I too have noticed fuel trims trying to remove a 8-10% most of the time and the car smells rich driving around town...

I don't believe this is a BMS issue since they cannot adjust closed loop parameters (correct me if I'm wrong) and it's possible I've got a leaky injector or bad 02 sensor.
