Recently installed the Cortex programmer along with several other mods on my 2011 F-150 (Harley-Davidson Edition). As I also installed a Magna Flow performance exhaust, an aFe CAI and throttle body spacer, it's hard to say how much the programmer improved HP. I does have incredible throttle response now. Very simple to operate, and their tech support is outstanding (so far). Currently running the pre programmed performance tune with the top speed raised. The are a host of other tunes available (tow / haul, mileage, 87 octane, etc..) and for the auto entusiast, sveral advanced modes, (spark adjust, etc.) I am completly satisfied.
