I went online recently and have had alot of fun drag racing. But some of these cars are just tuned amazingly. Now I know noone wants to share their exact drag tuning secrets but can someone enlighten me on what to worry about when tuning, how adding or subtracting from gears changes the speed and so on. Just the basics so I can enjoy tuning and racing on my own...PS I'm mainly interested in dragging FR cars, if that makes a difference.
