I have a digital prosport boost gauge which reads 10 psi when I'm in full boost. Then when I have my laptop hooked up to my SSAFC, it only reads 7psi. They are both tapped into the same vacuum source, and I have no codes for vacuum leaks or anything. My boost gauge prior to installing my boost controller pegged out at 6 psi, so I would imagine that it's not faulty. Any thoughts? I plan on getting a vacuum block in the near future, so that I can just plug all my stuff into that.
