I don’t think a Haltech ECU would pass inspection in most US states. I’ve had trouble getting my golf inspected with just a cat and a flash tune. There are emissions readiness monitors in most stock ECUs that need to show up for it to pass. The exhaust and tune i have aren’t even sold anymore because of the increasing number of legal restrictions. I get why it has to be that way but it does suck for people who want to work on their car.
