The Dyno Dominator LB7 is installed by plugging into the wiring harnesses found above the drivers side engine valve cover. Simply unplug the two stock connections and plug the Dyno Dominator in between. The switch can then be mounted in a suitable place in the cab. The switch has three positions; stock, 70hp and 110hp. Horsepower is gained by advancing and lengthening fuel injection timing. The Dyno Dominator also senses transmission slippage and reduces horsepower before slipping occurs. Use of Bully Dog's 4" exhaust and pyrometer gauges are recommended with the Dyno Dominator.
