We prohibit the sale of all tuners, devices or software that can modify vehicle performance, even if it does not remap the ECU or ECM or is described as diagnostic. This is to ensure compliance with EPA policy prohibiting products that defeat, bypass, or shut down emission control devices. (This is not intended to provide legal guidance on federal or state regulations regarding these products nor should it be considered an all-inclusive list of items prohibited) Our policy may prohibit items that could be legal, but from an abundance of caution, has chosen to prohibit.

California Air Resources Board (CARB)

CARB prohibits the sale or use of parts that will modify or defeat emissions systems in any 1966 and newer vehicles. This does not restrict sale of approved replacement parts, those granted an executive order (EO) number by the California Air Resources Board or race only vehicles. Items not approved by CARB will not be sold to California residents either by mail order, customer call center or website orders.
