What is the purpose of a wastegate?

A wastegate controls the maximum boost pressure your turbocharger can produce. It does this by diverting some exhaust gas away from the turbine wheel, preventing it from spinning too fast and creating excessive boost.

Can I change the boost pressure on this wastegate?

Yes, the included 7.25 PSI spring sets the base boost. You can swap this spring for different rates or use an external boost controller to achieve higher boost levels, depending on your engine's tuning and capabilities.

What does 'not CARB approved' mean?

CARB (California Air Resources Board) approval means a part meets specific emissions standards for use in California. Since this wastegate is not CARB approved, it cannot be legally sold or shipped to California.
