Predator praise.

Reviewed By Stephen B (Brick, NJ) Reviewed for a 2007 Dodge Charger —5/8/2008 6:22 PM

I heard so much about how great it was but being a sceptic and the unaffordable price, I was reluctant to get one of my own. If not for your price, I would still be without one. I am now a true believer in it. The downloads were a little confusing at first, but the frustrations I suffered are paying off now that it's installed. My car went from being a rocket, to a missile. I didn't think I could ever scare myself because of all the driver training I have had, but this product is aptly named, after an unstoppable, multi capable, killing machine from hell.

The Diablo has several options to choose from. I like the option the most that i could deactivate the active fuel management on my automatic Camaro SS.
