Put a superchips tune in yesterday. I love it!! The shifting is much more like a race car, hard when it needs to be but smooth when you hit the interstate. Disabled the AFM which that alone is worth it!!! Drove to a show today an hour away and even with the AFM disabled, I still managed to get 22/23 mpg at 75/80 mph. Very happy with it.
