Seems to work well. It is still a little early to be able to tell. Instalation was easy. I could tell a difference between the different types of tunes. The milage that I was getting on the highway was terrific to start with and I haven't had a chance to go on a road trip since changing the tune. Around town it is so hard to tell because of all the various conditions.
