The NX Diesel MPG-Max increases fuel economy in all load states, empty or while towing. Special mapping and the most sophisticated 2d digital controller available result in 1-3 MPG increases! The MPG-MAX system does not require a sustained high load state in order to provide maximum fuel economy gains. The MPG-MAX system uses a new injection management controller that allows for a small, steady spray of water/methanol to be injected across the entire power curve, at anything over normal cruising boost. This provides an increase in combustion efficiency which provides more power without injecting more diesel fuel. This increase in efficiency translates into an increase in fuel economy. Typical fuel economy increases are 10%-15% or 1-3 MPG. The MPG-MAX system has a secondary output that is used to activate a Power Mode. The more sophisticated microprocessor introduces a independently mapped second stage of injection. A larger nozzle is used to inject more fluid to make more power. The Power Mode activation point is adjustable for best performance. The net effect is smooth power in all engine load states with no combustion quench resulting in a true turn-on-and-forget system. The Super Bright LCD screen displays boost, EGTs, and injection pump output. This means a savings of $200-$300 in gauges you don't have to buy. Will not adversely affect particulate matter filter like some other power adders. Doesn't leave a signature? on vehicles computer so warranty isn't jeopardized.Comes complete with large 7 gal. reservoir for a truly complete system. True 2d mapping and 2 nozzles controlled independently for smooth power. The only system proven to improve fuel economy. Provides better fuel economy (1-3 MPG), more power (50-100 HP), and lower EGTs (150°-300° F).Dash mounted module displays real time no need for gauges.
