Yup yup, DBW is a mistake in my book, it makes the car seem more responsive (mostly just cus its opening the throttle blade more than you thought you were given your pedal input) but it can make a car tricky to predict and hard to tune. Just another thing getting in between the driver and the car imho (but I will say that the DBW is quite pleasant on the 350z - maybe b/c this car was built with a typically more sporty driver in mind?)
