Hmm....
I'm thinking about giving it a shot. I was surfing around and I stumbled upon a device called a non-relieving vacuum regulator. From what I read, it doesn't vent to atmospheric pressure to acheive the desired vacuum. The one I saw was an big industrial one though. I want to do some more poking around to see if I can find one that's a little more precision and MUCH less expensive.
One complication leads to another. Gotta love it.
In regard to what you were saying about the vacuum leak, etc. I guess I'll just have to but a brick behind my gas pedal so I can't floor it anymore! I don't think I should be expecting to get good MPG like that anyway.
Give a man a match, and he’ll be warm for a minute, but set him on fire, and he’ll be warm for the rest of his life.
