First time out

Are you running a stick or an automatic? The only time I've seen people use the line lock to stage is when they're rowing. Otherwise you're getting off with one foot on the brake and one on the gas. You'll have to play with it to find out what your car likes best, some like to leave off-idle like lenweiler said, others like to be rev'd up. My car happens to like leaving at around 3000 RPM, I keep my left foot on the brake and the right on the gas, when the last amber comes on I jump off the brake and floor the gas.
