Maybe im just out of the loop. I cant even find a boost gauge that shows negative on google. Vacuum sure, negative PSI, nope. Or maybe its alien technology hahaha.

6.5inHG sounds awfully low. Even with not running things off of vacuum a healthy motor still creates it with the throttle closed. I think the numbers are just a placeholder for things to come.
