Having an automatic retard box allows a street/strip car to be much more spontaneous. Allows you to pull more timing than required for added safety margin while spraying on pump gas, without giving up any NA power or mileage. When I pull up to a spot I don't have to get out of the car to adjust timing or air pressure, just flip the switch and reach behind the pass seat and turn on the bottle. Retard box then takes care of the timing, 'tamer takes care of the traction, nitrous delay sneaks the nitrous hit in right around clutch lockup where it least upsets the chassis/traction.
