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.

I think the Diablo Sport Tuner is a great investment for the money,it does everything they say it will do. And the menus are easy to navigate. It really woke up my Silverado, the multiple truck use is a nice option agreat s is being able to turn off the active fuel management
