Lower EGTs 100-300 degrees and increase HP by 65+ with a cleaner, cooler running Chevy/ GMC LBZ / LLY/ LMM / LML / L5P Diesel Duramax! The Snow Performance Diesel Stage 2 Boost Cooler is available for all Duramax owners looking to have the benefit of water-methanol injection through out the Duramax's boost range. The Stage 2 utilizes a progressive VC-50 controller (52mm gauge) that commands two water-methanol nozzles that proportionally inject more or less according to boost pressure. Start and full points are adjustable for engagement and delivery curve to match what the engine requires. Proportionally injecting according to boost pressure gives an accurate delivery of water-methanol and allows cooling and performance improvements over a wide range for improved drivability. The VC-50 controller (52mm gauge) offers the functionality of a boost gauge and water-methanol controller all in one! Highlighting a 7 color (Blue, White, Red, Yellow, Orange, Purple, Green) OLED screen displaying boost, percentage of injection, secondary nozzle activation, prime button, and 2 fault codes directly on the screen you can tailor the controller to match your OEM gauges or mix and match up to two colors. 7 Gal Tank included for trip ready installation. Recommended for all daily driven Chevy / GMC Duramax's that see light towing.
