Turbo XS High Performance Boost Controller

Utilizing a uniquely engineered ball/spring mechanism combine with an adjustable bleed valve, the High Performance Boost Controller allows you to spool your turbo to full boost up to hundreds of RPM faster than stock! The adjustable bleed mechanism lets you minimize the massive boost "spike" that can occur with poorly designed ball/spring manual boost controllers.
