The all-new VC-50 water-methanol injection controller from Snow Performance gives you the benefits of a boost gauge and water-methanol controller/fail-safe all in one! Heavily loaded, the VC-50 controller comes with a built-in manifold absolute pressure sensor that proportionality injects more or less water-methanol according to boost pressure. Start and full points are adjustable to match what the engine requires. New dual tone 7 color (white, green, blue, red, orange, purple, yellow) OLED screen shows boost, percentage of injection, low level, second stage activation, and fault codes in a bright easy-to-read screen.
