Standard: Simple, inexpensive, and effective way to control your boost level and generate more power from your engine. Bleed type boost controller allows you to increase boost approximately 12psi over your wastegate boost setting.
High Performance: Utilizing a uniquely engineered ball/spring mechanism combine with an adjustable bleed valve, the BC-HPBC 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.
