You benefit more from gimmicks!!
A "gimmick" most would think of would be something that is not needed, or beneficial to their particular car, like say a T88 on a bog std sierra cossie, so this would be a gimmick to most but to a few invaluable, what did MSD do before the air to air come along ?, did you use with perfectly good results the amal valve, or have you never ever set a car up on a amal valve ?, or did those that you set up on amal valves all fail badly ?
