Force Performance Chip/Programmer compatible with Ford Ranger 2.3L, 2.5L, 2.9L, 3.0L and 4.0L - Increase your Horsepower & Torque. Gain More MPG, Save Gas, and increase your Fuel Mileage!

In my experience this product worked as advertised. The only problem was that it created a 'check engine' error for my vehicle, '04 Ford Ranger Edge - 4.0L, that would not go away consistently. It definitely improved throttle response and, seemingly, shift points. I would've liked to have had a chance to find out if it would've improved my MPG as well as it was on course to meet all claims made in the item description. I would definitely recommend the product to others as they may have a more 'robust' ODB than I and therefore better luck.

improved power not sure about gas mileage

After only one tank of gas, I received 3 miles per gallon more. The truck runs so much better now that I’m very pleased with this product and would recommend it to anyone.

Lower you're expectations, apparently mine were too high.. im sending it back. Thought it gained some horse power but that was just wishfull thinking. It gave it a little more torc but not $60 worth. Oh and now my check engine light will periodically come on and go off with no apparent change in the way it runs.

This thing worked great on my '00 Ranger 3.0! Definitely has more power and is more responsive!

Started too come apart after a month didn't really tell a differents.. and not sure if it was working or not

It does not work at all.

Works as it should. My 3.0 l has noticeably better throttle response and it did gain approximately 4 mpg. Easy install. I would definitely recommend to anyone.
