How do I find a BSFC for a specific vehicle?

Hello again everyone.

I was going to use a vacuum gauge to try and zero in on a good FE/RPM range. After reading the replies I got to the thread I started on it, it seems that the information provided by the vacuum gauge won't be enough. A Brake Specific Fuel Chart (BSFC) might be needed to find the best "bang for the buck" FE/MPG range.

My question is......how do I find one? I've looked online but not knowing enough about such things, maybe I'm looking in the wrong places? Is this something that needs to be done at a place like a dyno shop or someplace similar?

I'm getting great mileage now but am always wanting more. I'm always wanting more time to work on the truck too, but time is usually at a premium. Too many ideas and too little time to build.
