MSD Engine RPM Limiter 8734; Launch Master for 1999-Up Ford 4.6/5.4L MOD (Coil-on-Plug only)

This 2-Step connects right to your late model Ford to produce consistent launches and quicker 60-foot times by setting an rpm limit to stage with. When activated, the rpm will be held at a steady rpm and once the green light comes on, release the clutch and take off. The rpm is adjusted with two built-in rotary dials ranging from 2,000- 11,900 rpm in 100 rpm increments. A handy LED shows when the launch rev limit is active.
