Pretty simple... as soon as you final stage you hit
the button... then it depends on which you do... box
racing or bottom bulb... for box you let go of the
button as soon as you see the first light coming down
then go to the floor with the gas... it'll hit your
2 step rev limiter then it will launch at the right
time if the box(delay) is set right.... if you bottom
bulb you go to the floor when the light comes down
and let go at the last yellow... you may need to
change your set up on the car for bottom bulb as
it might launch too quick... need to check that
