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.

Rated 4 stars only because I had some trouble tuning my vehicle and called Diablo twice first time was on hold for 50 min and second time someone answered after 55 min and told me everyone had went home for the day they took my name and number and said someone would be getting into contact with me the next day they never did so good luck if you have any trouble I figured it out myself .
