Glad you had fun! That's what it's all about. There's lots of guys in here that will give you excellent advice. For now, leave the car alone. Turn all of the nannies off and forget about playing with the settings. Those modes are developed around a race track, not an autocross track. You'll be turning tighter, and there will be times when you want/need the rear end to rotate around. If you have it in a sport mode and you try to spin the ass around, the computer will think something has gone terribly wrong and will cut power big time. Get an instructor, go for rides, and watch all of the fast guys.
