Upgrade your Duramax MPG with the only system proven to increase fuel economy in all load states – empty or while towing. The Snow Performance MPG-MAX™ is available for all Duramax applications and comes with a propriatary injection boot for a clean custom install. The Snow Performance MPG-MAX Duramax (LB7 / LLY / LBZ / LMM / LML) water-methanol injection kit utilizes a fully adjustable progressive controller that commands two stages of water-methanol that proportionally inject more or less according to boost pressure and EGTs. Proportionally injecting according to boost/EGTs gives a unparalleled delivery of water-methanol for all towing applications and provides the largest increases in MPG and cooling.
Built in modes (Power/Towing) allow the user to seamlessly switch between two programs for daily driven use (Power Mode) and while the vehicle is towing (Tow Mode). The net effect is smooth power in all engine load states with no combustion quench resulting in a Fuel Economy Increase of 1-3 MPG, HP increase 65+, and reduced EGTs (100-350 F). The MPG-MAX offers true plug & play functionality that will not affect the electronics or the warranty of the vehicle. Complete with heads up adjustable LCD screen displaying boost, EGT temps, percentage of injection, and second stage activation for accurate monitoring and on the fly adjust-ability! Learn More
