The Snow Performance MPG-MAX VW TDi water/methanol injection system provides more power, and excellent fuel economy increases. The The MPG-MAX system uses a new injection management controller that allows for a small spray of water/methanol to be injected across the power band. 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. Independent testing by Diesel World Magazine showed fuel economy increases of 5%-15% (4 MPG on the TDi)and Power increases of 35 hp/ 40 lb. ft. in a 2010 Jetta TDi - see March 2010 Diesel World Magazine:
The MPG-MAX system has a secondary output that is used to activate a Power Mode. This introduces a second phase 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. This allows for more injection when more power is needed.
The MPG-MAX system has been coupled with the Snow Performance 2.5 Gallon trunk mount reservoir to provide a large fluid tank. This will provide long range and includes the necessary installation hardware. Also, the system has an LCD screen that displays boost, exhaust gas temps and injection pump output.
