The Boost Controller allows you to control the amount of boost that is forcing air into the engine. Combined with boost control, you can also create a timing map based on boost pressure. Through the advanced View software, you can create a boost map for the entire run. Values are based on pressure sensors including dual 4-BAR internal (good through 75 PSI). Their is also a boost pressure activation output and a safety overboost shut-down feature. Includes an additional feature that can retard timing in order to help spool the turbo's.
