Pacific Performance Engineering, the Duramax specialists, brings new technology to all existing Duramax Diesel Trucks. Similar to how the Duramaximizer and Xcelerator have revolutionized all Duramax trucks, this new product will set the standard in prolonging the life of all Duramax Trucks. This new product is called the High Idle/Valet Switch and has two great features. The first feature of the High Idle is designed to increase the RPM of the Duramax Truck. While the engine is running, and in the park, the cruise control device can be switched on and the engine will begin to increase the RPM to 1,200. The High Idle can also raise the RPM to 1,800 by pushing on the acceleration switch for the cruise control. The High Idle switch eliminates the use of another person stepping on the accelerator such as in the case of trying to jump start another vehicle. On those hot or cold days, you can set the idle up to create a comfortable air temperature for the interior. Turning the High Idle switch off is just one click away. The High Idle can be switched off directly on the mounted switch, or another push on the cruise control device can lower the RPM, and stepping on the brakes lowers the RPM. Due to the safety feature of shifting gears, the brakes must be applied before changing from the parked position to any other setting. This prevents the transmission from any damage while the High Idle switch is enabled and the RPM is increased. The second feature of the High Idle switch is called the valet mode. This feature is designed to protect the vehicle from anybody who might want to abuse the power of the Duramax Diesel. Once enabled, the High Idle disables all performance enhancements made to the Duramax such as power chips, propane boosting equipment, and even the Xcelerator and Duramaximizer.
