'96 Ford Explorer 4.0L

Hi guys, Sometime back, I installed this AquaTunePlus unit on my '96 Ford Explorer with the 4.0L engine. I came up to your area for a seminar and dropped by to see you. You noticed that I had installed the wrong venturi injector nozzle. You replaced it with the correct one and made some very minor adjustments and now I am getting 22mpg in town where before I had been getting only 16mpg.Thanks again for your assistance.
