Waht should the boost gauge read at idle? I've got "20" on the vacuum side, when I rev it it goes up to about "0" maybe alittle above that/ :confused:

Mine is at 20 or just below 20 on the vac side and goes past +5psi when I rev. I dont know if it will go any higher because I have never put the peddle to the floor while reving it.

18-22 inches of vacuum (Mercury) at idle is pretty standard. Automatics in Park/Drive may be a bit lower around 16/17.
