Boost Controllers

Standard Boost Controller - Simple, inexpensive, and effective way to control your boost level and generate more power from your engine.

The TurboXS Standard Boost Controller is installed in line with the pressure hose running from the positive pressure side of the turbo to the wastegate actuator system. It can be used on vehicles with internal and external waste gate systems and on vehicles fitted with factory electronic boost control systems. Simply cut the waste gate pressure hose and insert the supply pressure hose onto the brass nipple of the boost controller. Insert the waste gate supply hose onto the blue colored nipple. Secure the hoses with hose clamps.  Alternatively, use the hose extension which eliminates the need to cut the pre-existing pressure hose. The Boost Controller can be mounted with the mounting bracket. The boost pressure is adjusted via the adjusting screw located internally on the top of the TurboXS Boost Controller. The vehicle’s boost pressure can be increased by winding the adjusting screw in the counter-clockwise direction. Once the boost pressure has been increased, winding the adjusting screw in the clockwise direction will decrease the boost pressure. Typically, one (1) full turn of the adjusting screw in the counter-clockwise direction will result in a turbo boost increase of one psi.

High Performance Boost Controller - Adjustable ball/spring design gets you to full boost hundreds of RPM faster than stock!

Designed for those who want the ability to radically increase their boost levels 1 to 30 psi above stock, but don’t want to pay hundreds of dollars to do it. The TurboXS High Performance Boost Controller (HPBC) is the right choice for simple, accurate and reliable high level boost control. The HPBC has two (2) boost control mechanisms built into it. One is a ball and spring mechanism for large and coarse boost pressure increases and the other is a bleed valve system for precise boost pressure setting. The ball and spring mechanism keeps pressure out of the wastegate until the preset boost level is reached, significantly reducing wastegate creep and providing quicker turbo spool up. Boost is adjusted with the simple turn of the screws using the included 2mm hex key.Kit Includes: High Performance Boost Controller, 6mm vacuum / pressure hose, Mounting Bracket, 12mm hose clamps, 2mm Hex Key. Installs as easily as our Standard Boost Controller: Simply cut the waste gate pressure hose and insert the supply pressure hose onto the brass nipple of the boost controller. Insert the waste gate supply hose onto the blue colored nipple. Secure the hoses with hose clamps. The Boost Controller can be mounted with included mounting bracket.

Dual stage Boost Controller - Two preset boost levels allow you to switch from "street" to "race" boost with the flip of a switch from inside the cabin - even while under full boost

All the things that you like about the Standard Boost Controller with the added ability to switch between 2 pre-set boost levels from inside the cabin - even when under full boost!  The TurboXS Dual Stage  Boost Controller is installed in line with the pressure hose running from the positive pressure side of the turbo to the waste gate actuator system.  A switch is wired back to the cabin to switch between boost levels.  The switch is lit when on high boost. The kit includes: Dual Stage Boost Controller & Mounting Bracket, Electrical Plug and Wiring Loom, 6mm Pressure Hose, Control Switch, and Necessary Installation Accessories. It can be used on vehicles with internal and external waste gate systems and on vehicles fitted with factory electronic boost control systems. (Electronic boost controllers must be disabled.)
