The Stage 3 Diesel Boost Coolers are the most comprehensive water-methanol injection kits Snow Performance makes. This controller senses not only manifold boost pressure but also exhaust gas temperatures. Using two inputs allows for the smoothest injection control. More importantly, it also keeps the EGTs as low as possible if they begin to climb, even if the boost stays constant, the Stage 3 controller will read this and inject more water-methanol to compensate. The adjustments to the delivery on the fly are accomplished with two easy-to-use push buttons, allowing for more or less injection, or switching from both boost & EGT referenced injection (smoothest, best for towing and EGT control) to just boost referenced injection (most responsive, best for performance and racing).
