Snow Performance's 2D mapped progressive controllers are a TRUE two dimensional system meaning if either input signal goes up or down, we vary the injection quantity by increasing or decreasing the injection rate. Our Stage 2D Boost Cooler for Mitsubishi vehicles (#20009) injects variably according to boost and variably according to the MAF sensor signal. So, for a given amount of boost, say 10 psi, if there is a small amount of airflow, we will inject less than if there is a great amount of airflow. Likewise, for a given amount of airflow, if the boost is higher we will inject more than if the boost is low. Varying the injection according to BOTH input signals is what makes a map 2 dimensional and more correct than the delivery of the Competitor "C" kit.

Snow Performance's Stage 3 Diesel Boost Cooler kits are also truly 2 dimensional, injecting variably according to both boost pressure and EGTs. That allows for the most accurate injection while towing or even just cruising around, resulting in smoother power than the Competitor "C" 1 dimensional and threshold type of delivery or the Competitor "Purple" staged injection system. Snow's controller has a master adjustment to change the delivery aggressiveness - no need to hook up to a computer or download anything - it can be done on the fly very quickly and easily. It can also be switched from 2 dimensional boost and EGT mapping to just boost mapping for a more responsive injection when racing or sled pulling - with just a flip of a switch! No computer hookups and no wire cutting. Easier to use, less expensive, and better performing.
