for those who are skeptical, cynical or simply curious about Ashs tuning, you should be glad to know that his ECU program passses the most strict smog regulations. I live here in Southern California and had my Z smog tested yesterday with Ash's ECU program installed. My Z passed all the inspections and tests effortlessly. Although i sound surprised, i actually expected Ash's program to pass emissions, because Ash leaves the fuel maps that affect emissions unaltered for this specific reason.
