Just looking for a mild tune , sounds like I keep my warranty , and go Ford .If you're talkin about the ford company's upgraded performance tune there's lots of people on here running it. Plus side is it's warranty friendly an gives a nice boost....down side is the other tuners like unleashed, Livernois an 5 star offer more performance but you risk losing your warranty. Plus the non ford tuners offer performance tunes in reg octane vs ford which is premium fuel only. I run the Livernois an love the power.
