I was talking with a friend who works out of his house on powerstrokes. Just shootin the $hit, and showed him a 60psi air gauge. I asked why it wouldn't work. He said because it doesn't read vacuum. The hole tapped for the boost gauge fitting is vacuum not pressure. He sia if It were ever installed, it would just sit there. WTF! {It's a moot point, because I have a boost gauge}. But I had to stop and think about that. The whole purpose of a turbo is positive pressure, when spooling anyway. Letting off would draw vacuum......am I bassackwards on this er whut.
