Here's a perfect training video I just made the other day.
YouTube - Lightning vs Lightning inside cam
It shows from start to finish on a track.
I always drive around the water box, and back up into it.
Then just spin your tires once real quick to get any dirt off.
Pull up and do a burnout, not a smoke show, just heat them up some.
Then pull to the line.
Do not double stage, it annoys some people.
Pull up till your first yellow staging light go on.
Let the other person get there first yellow staging light, then pull forward and get both yellows, let them do the same. Then power brake up your rpm's till the truck wants to pull forward(the rpm range all depends on if you have a stock or aftermarket stall converter) I'm still on stock, so I usually go to around 1200-1400rpms. Make sure overdrive is off. Last yellow light you see, mash the pedal. By they time the truck is moving, the light is already green.
Away you go.
Hope this helps some.
