Turn up the boost! With more boost and performance changes from the SLP Flash Tun’R’s custom map, this Stage 2 Kit pushes your turbo’s performance to the next level while still using 91 octane pump fuel. Not only does this kit add horsepower, but it also gets that power quickly to the snow with our Power Shift™ Clutch Kit. In addition, the SLP Competition Series™ Lightweight Silencer provides a performance growl and gives the sled a nimble, responsive feel (10 pound weight savings). For best performance use 0.5 oz Lucas Octane Booster per 1 gallon of 91 octane fuel.
