Very good upgrade for added stopping power for my GTO.

I'm getting about 3- 4 mpg better, performance is difficult to rate. It needs more tuning options for the novice who is not familiar with the settings. There is not enough info with the product that tells you what different features do. Install is easy, as long as you have some computer skills, basic skills. Big price tag, not sure if its worth the bux.
