I put this on hearing good and bad, some couldn't tell a difference and it worked magic for others. I'm really impressed with it, gained 2 MPG's after installing and she has a little more pep in her step.
Best upgrade yet!

Works as advertised! Wish it was Mac compatable. Could use more detail on all the options (there are a lot of them). Noticable differencein power, MPG's, better/smoother shifts with bigger wheels/tires.

I have only been using the 87 Octane tune for a week but I definitely feel better throttle response and more pull and performance. I readjusted the tire size for proper speedometer readings and will be curious to see what change if any I get with my gas mileage.
