Ok I have no idea how to tune a car in this game. I NEED MUCH HELP! Some things on what to change, or how they should look, would be very helpful. Right now I'm playin my career with a turbionium, but when I go on live I will be using a 350 z so if some one has a really good setting for the 350 z I would really apreciate if they told me how much of each setting to use. Thnx.
