Sorry. Yes....0" and 5" is inches of vacuum.Hot Rod Harry said:Glad you asked that..I was wonder the same thing.
Inches? Inches of vacuum?
Cool! Thanks! Will do!Hot Rod Harry said:I guess you should just give Rick or Linn a call tomorrow if you can. That would be your best bet since he did your chip originally and ask him on the phone. I think I remember Uncle Jimmy V. saying he uses Ricks chip and every time Jimmy needs a new tune...Rick does it for him with no prob. Something like that..just trying to help

LOL, it's good to see someone was awake in physics class.IWRBB said:The KB has a bypass valve jsut like the Eaton does, so no boost can happen if vacuum is present.
There's no possible way for boost to start at 5" Hg vacuum. Boost is air pressure above 1 atmosphere. If the intake has vacuum, boost is not possible.
What you are thinking of, I believe, is at what point the dump valve closes. This is an old trick the L guys have been using for years. The dump valve closes earlier (at a higher vacuum), so you are guaranteed boost as soon as it's possible, not when you dump valve finally gets around to closing.
