I have not driven with it off one time yet... i now when it was raining and i wanted to see how it would react i hit the gas coming out a parking lot and it shot the car straight. i'm fine with that, knowing there is way less of a chance of the car spinning out when wet or something. As far as accelerating and when passing cars, my car never loses power or anything with the vdc on... even when i go from a stop and hit it from 1st it still goes, granted it doesn't burn out, but when tires are this expensive i don't mind it not burning out
lol
