Subaru WRX Boost Controller

Description

Subaru WRX Boost Controller 2002 – 2014 Turbocharger Waste-Gate Controller

The Turbo Authority Boost Controller is a fully independent, spring-actuated waste gate boost controller. It bypasses the factory vacuum canister to provide a much better and controllable boost curve.

In order to run higher boost pressure than the factory settings, you will need a tune – such as the Cobb tuning.

The factory compensating canister starts to leak boost pressure at around 40% of the peak boost pressure to control the boost curve – which hurts performance. This WRX Boost Controller does not bleed off boost pressure under the set max, which provides a quicker spool time, more turbo efficiency, and more boost – which translates to power.

This is a simple, bolt-on upgrade you can install in your driveway in 20-30 minutes.
