The Key is "Additional Expense", it wasn't cheap, but it comes with free tunes and will reprogram my car in less than 3 minutes. There is one tune Faster than the one that I have in, but that is reserved for FAST back road driving, or if it ever gets a little time on a track.
Hopefully you don't take that big of a MPG hit
