BNR S-Line Budget Wastegate Actuator for your Gen 1 Cruze, Sonic, Trax, and Vanderhall Venice! Fits stock turbocharger as well as BNR GTX250, GTS250, and many aftermarket turbochargers. Uses a metal piston design instead of rubber diaphragm like other competitors.
This is our budget wastegate upgrade. This budget wastegate is directly comparable to every single other wastegate on the market for the Cruze/Sonic/Trax/Vanderhall but at a more realistic price - We aren't charging a massive markup like some competitors are.
The stock wastegate actuator is super weak from factory on 95% of Cruzes and Sonics. This is why even with a tune for 20+PSI of boost, you see a lot less. This is also why you see P0299 on many 1.4Ts. Changing to this actuator will fix that problem and let your turbo make full boost. On some cars this will be a 10HP upgrade. On cars with weak stock actuators this could add as much as 40-50HP.
The amount of preload is adjustable simply by tightening or loosening the actuator rod. We recommend starting with one full turn of preload and testing your boost from there. Once you've determined where the boost is sitting, you can decide to go tighter or leave it alone. Too much boost will trigger an overboost condition on the ECU and put the car into "limp home" mode, where you will lose all boost. This likely means you have tightened it too much, and need to loosen the rod some.
It's hard to say an exact power number as the stock actuator could hold anywhere from 15-23psi depending on the one GM used on your car. If your car is holding 20psi with the stock actuator, this will add anywhere from 10-20HP. If your car makes 15psi on a tune, this will add as high as 50HP to your car.
