New MSD Soft Touch rev limiter and 3000,6000,7000 and 8000 chips. No box, item was stored in a parts drawer in NASCAR race trailer.

MSD Soft Touch rev controllers use sophisticated computer circuitry to drop spark one cylinder at a time, until your engine is at or below its maximum rpm. Those cylinders are then fired on the next cycle, to prevent them from loading up with fuel. The result is smooth rev limiting action without all the rough stuff. There are two versions of the Soft Touch rev controllers--one for MSD's 6T, 6TN, 6HVC ignitions, and one for OEM electronic and points ignitions. Both come with 3,000, 6,000, 7,000, and 8,000 rpm plug-in modules, and can be used with other modules or MSD's RPM module selector.
