This device works great. GMC Runs better, more power, shifts better, no noticeable increase in fuel consumption. The AMF was a bad idea from GM.

I noticed the engine opens up now when I want it to. Before the response wasn't there. But it wasn't easy figuring out the shifting configurations. I had to research some forums but there's not much shared about it. I paid $275. Great deal
