Its very easy yea like 60 psi coming in around here. You can bootleg it or go legal but Ill guarantee in my jurisdiction you dont just call gas company and tell them to jack pressure to 2 psi aint happening there is a process. how about those regulators dont you have to vent to outside ?At least one California supplier supports 2 psi at least for new residential construction. https://www.socalgas.com/for-your-business/builder-services/elevated-pressure I don't know if they support retrofits. It should be easy enough in most areas, because the regulator at the home is supplied by pressure much higher than 2 psi.
