Ok guys and gals well it a simple but hard question? well has any one put a 2 step or stutter box on the ms3 or ms6. If you did which one did you use. I don't want some to tell me hold it at the rev you want and let go the clutch. It is different everytime i know. the honda and dsm are using them but they are going msd ignition systems. So any real racers out here let's see what you guys have in feedback ok Thanks (drive2)
