What can I do about the throttle lag that I often experience? My car requires that I think ahead so much that sometimes it's not safe. Yesterday I almost got rear ended in traffic. I punched it and the car said "I'm not ready yet". I don't like this adaptive drive. I heard about some kind of bypass module....
It doesn't do this in Sport mode.

Buy a Sprint Booster. You can do a search on e60forums.com and many people there have bought that to solve exactly what you are talking about. I got one and it's fantastic!

I think I found the email address for the seller. We'll see what happens. Thanks for the recommendation.
