Tunes like this work by dumping more air/fuel into the engine, making more HP. They don't mess with suspension or throttle/shift points at all.

The 2 are complementary, not exclusive. A tune like this will typically make a bigger difference in the feel of the car than sport mode, sometimes dramatically so.
Thanks for the explanation. So....are you putting it on your new ride? I've been apprehensive. My tune is still sitting in the box. :/
