Acceleration Comparison w/GT500

I wouldn't even really consider this a race, but its the first fun I've had since the trucks been running with the turbo. I rolled up next to a older guy in a GT500 and never really expected him to give my truck a 2nd look. Light turns green and I somewhat roll out, well he jumped on it pretty hard, so I stood on it. I got a little excited and stayed in the throttle too hard, spun all the rest of 1st and 2nd. Still staying with him, then it got traction and I took off and left him. He wouldn't come back up next to me after that.
