So I've maxed out my stock 8psi gauge and I've seen a few people with the Boost/Vacuum gauge that mounts where the stock one is, but goes down to like 15 vac. and up to 30 psi, it's a full sweep and looks stock. If anyone has this gauge where did you get it? I've only seen a few and don't know if it was stock in dashes on different models, or a custom job. Thanks for any help.
