I don't have direct experience with that, but I would highly doubt it would actually add any HP. The ECU's in later model cars (say post 2000) are pretty well optimized, unlike older vehicles. A lot of times these "tuners" will just mess around with the throttle by wire to make it feel peppier, but it doesn't really add any HP.
