Snow Performance Stage 3 Diesel Controller

The Snow Performance Stage 3 Diesel Controller is a water-methanol injection kit designed for turbo diesel pusher RV owners seeking improved performance and engine longevity. Featuring a 2D mapped controller, it commands injection based on boost pressure and exhaust gas temperatures (EGTs) to maintain significantly colder air inlet temperatures, resulting in 100-300 EGT decreases, reduced emissions, cleaner engine components, and enhanced fuel economy. This system provides an additional 65+ horsepower, making it easier to tow heavy loads and climb large hills. Its non-invasive design allows for easy mounting on the steering column or dash without drilling or interior marring, and it functions as a boost gauge, water-methanol controller, and EGT monitor in one unit. The kit includes a 40-foot harness for rear motor applications and a 7-gallon tank for trip-ready installation, offering a plug-and-play solution for demanding diesel RV owners.

Designed for all turbo diesel pusher RVs, the Snow Performance Stage 3 Boost Cooler is ideal for vehicles requiring colder EGTs while towing heavy loads. Compatible with various models, it is especially suited for diesel RVs that benefit from enhanced cooling and performance. The system is easy to install, with no invasive modifications needed, and includes all necessary components for a straightforward setup. This kit is recommended for diesel RV owners seeking a reliable, high-performance water-methanol injection solution to improve towing capacity, engine longevity, and overall efficiency during heavy-duty use.
