This question probably belongs in the noob section... anyway, I purchased my sti a few months ago. The previous owner traded it in, the dealership had a local performance shop (forced air tech, awesome shop) rebuild the engine. The previous owner sold the accessport with the vehicle but I've been told it won't work since the engine has been rebuilt. can I plug it in and check? I don't want to screw anything up.. What are my options? Do I need a new one?
