I think there is a lag regardless of the build date... It was obvious today after test driving a car with June build that the car truly has a 1 to 1.5 seconds of lag before the car actually start to accelerate hard. I'm surprised to hear Alan state he has zero lag.
Let me also be clear on what I mean by lag... you're at a full stop and you punch it, that's where I notice the lag, its not while the car in motion.
Maybe that's just the way it is and I have to accept it...
