2004.5-2005 6.6L Duramax LLY 6 Position High Idle Switch

Just like our 5 Position switch, our 6 Position switch gives you command over more or less HP & TQ by simply turning the dial left or right until it clicks (must have SOTF tuning installed). Depending on your vehicle, our switch will utilize your truck’s Fuel Temperature Sensor, Crank Case Pressure Sensor, or Intake Air Temperature Sensor. With our High-Idle option, you can turn up your engine’s RPM’s to warm your truck up faster on cold days, or utilize the PTO function on your work truck.
