This MSD Launch Master 2-Step Rev Limiter for 1999-10 Mustang GT is a great way to improve your consistency at the drag strip. This kit is easily installed by plugging it inline with your factory coils. The only splicing you'll need to do is if you plan to use the factory clutch switch for activation, otherwise you can simply wire it to a momentary switch (not included).

Launch RPM is selected by using the 2 simple rotary dials on the unit. It can be set anywhere between 2,000 and 11,900 RPM in 100 RPM increments. The Launch Master unit even has an LED light to let you know when it's active.
