The Turbosmart GBCV will allow boost pressure to be adjusted above the standard setting To avoid using un-reliable methods of increasing Boost, such as shortening the actuator rod.

This causes spring bind in the actuator and restricts flow through the wastegate. It avoids having to replace wastegate springs, which only give a fixed increase, which is not adjustable.

Turbosmart has a feature called a Gated System - unique to Turbosmart. This delays the pressure signal from entering the wastegate, which inturn spools up the turbo faster, resulting in more boost at lower RPM.

Setting the desired boost pressure is made easy. Simply adjust the Boost Dial on the top of the unit, without the need for any tools. Turbosmart Boost controllers are capable of increasing boost pressure to the threshold of your turbos capacity.
