      2002 Ford F150 FX4

      I have mixed feelings about this item. I wish there were more tunes for it even if you have to buy them. The canned tunes are okay, the most obvious gain is to be able to firm up and change the shift points at WOT. This has helped a little with performance.

      Don't waste your time unless you are using the tuner for a custom tune.

      Easy Power Adder

      I would venture to say this is on of the easiest mods you can do, if you can operate a smart phone you can tune your car. It is a more tech oriented mod rather than mechanical. The tuner works perfect all the time. Helped with the shift point towing a dirt bike trailer over passes, motor seems to have an easier time of it now. If I had to be really picky I would say the only thing that could be improved on this tuner is the finish. The black plastic shell gets dirty and scratches easily, like most gloss black finished items. As always quick and easy delivery from American muscle.

      love the difference in seat of the pants feel

      Awesome product. Took a few minutes to get all set up seeing that it is the first tuner I have used. Easy to navigate the tuner. Could feel the difference soon as you put it into drive. don't know why I didn't use a tuner sooner.
