You Tube has some stuff too
I have tried many tricks on my Jeep (the ole tornado, and several other gimmicks)
The most rewarding was installing a O2 sensor and a "Air/ Fuel Ratio Gauge" and using my in dash "Vacuum Gauge" to help me select the best Jets to run in my Carb, and power valve. As traditional ways I was shown, left too much guessing and error, in my eyes, anyway, I had been trying to achieve at minimum a 10% MPG gain, as promised by other carbs and gimmicks
I kept accurate adjustment and tuning records for nearly 2 years in my logbook.I was about to give up.
My Jeep is Heavy, I carry way more crap than the average Joe (I need it, I got it!). We weighed removable crap, and guessed at other stuff, my buddy and I came up with 400-500 lbs. Brush guard, rear "air tank" bumper, 80' 3/8 cable, 5 extra gallons fuel, 21 gallon over-sized fuel tank, air compressor, train horn, door steps, tools, spare parts, 3 coats, food, water, ax, shovel. And more!
There's no tellin' what I might gain if I were the "unprepared type"
Right now 18, MPG w/ Holley 390 CFM 4 bbl, that's about 2 more MPG than with the stock 2 bbl BBD, and I was much lighter, when it was on!
Mega power, if I get on it, and MPG, I've never had before. All on my 258, 6 cylinder!
Hope this helps
