Where to install Stillen Supercharger in LA?

Also only the Stillen Supercharger is CARB certified, with the Stillen tune. Thus if you obtain a custom tune, you may not pass the emissions testing -- or you should be prepared to default back to the Stillen tune at the time of testing. Hence, you should check with Stillen regarding this issue.
