GFB Boost Controllers

GFB boost controllers in NZ stock. A boost controller is one of the simpler ways to raise boost on a turbo car, because it changes how much pressure reaches the wastegate actuator rather than touching anything inside the engine. GFB make both electronic and manual versions, and the right one comes down to how much control you want from the driver seat.

Electronic boost controllers

An electronic controller lets you switch boost levels on the move and hold a target as conditions change. See the GFB electronic controllers and parts, or the wider electronic boost controller range to compare brands.

Manual boost controllers

A manual controller is a bleed valve with no wiring and nothing to fail electrically. You set it once and leave it. Look at the GFB manual controllers or the full manual boost controller range.

Other GFB boost parts

GFB also make the gates and actuators the controller is working against, so the whole system can come from one brand. See the GFB external wastegates and the internal wastegate actuators.

Choosing the right controller

If you only ever run one boost level, a manual controller does the job. If you want a low setting for wet roads and a higher one for the track, go electronic. The electronic versus manual boost controller guide compares the two properly, and the full GFB range has the rest of their parts.
