I bought a plug in power booster device off of Ebay. It's supposed to fit the 2 liter and yours. I went on a recent trip to Tennessee from Ohio. Without the chip i had to put the gas to the floor going uphill. With the chip plugged in, i didn't have to do that and it seemed to get 1 or 2 mpg better gas mileage. It seems to set the shift points differently. It plugs into the diagnostic port. I bought the cheapest priced one as they all look the same, but listed at different prices. I also have a K & N air filter. After the trip i scheduled a service appt to have Ford reprogram my computer for more power. We will see what happens.
