    Your experience is typical of most 'chip' buyers. Modern cars don't have 'chips' that can just be added, they have computers that require reprogramming. That is accomplished by hooking up a pc to your vihicle and, with the right software, adjusting parameters while making runs on a dyno. You might find a Ford performance company that has parts that would work on your Navi, like Roush. They show supercharger kits for Mustangs and F150s. Big money for big power, lower economy.

    It really all depends on the engineering done on that chip. In general, these "plug-in" chips are pretty crude stuff--they screw around with timing, or they try to fool the coolant temp sensor, etc.---the real power and noticeable differences come from sophisticated re-programming done with special equipment.

    Ask for your money back if you don't notice any difference, and if they balk on you threaten to spread your experience all over the Internet. That'll get their attention if you do it correctly. There's the eBay feedback, YELP, the Navigator forums, Better Business Bureau in their locale, and the local DA's Consumer Fraud office. Make out a list of where you're going to post and send it to them if they refuse to help you.

    I wouldn't put much into any high performance chip unless it's purchased at a dealer that would also install and warranty it. I've referred many customers to Mopar performance personnel who put "hot chips" in Dodge SRT-4 as well as turbo upgrades. As the first post mentioned dealers and high performance specialist are your safest route and may not cost much more than the $400 you spent.
