I have my old predator and I just bought another rt classic so my last one made the 12 second club so was going to try duplicating it as best as I can. But much to my surprise it already has a diablo tune in it. So wondering if any one has a factory tune i can get so I can load on my diablo. Then I will be able to tune car. Before everyone says buy a new one I will still have the problem, although I'm curious about predator x for phone but don't know if I can adjust parameters such as timing in each gear and fuel also. Thanks if anyone cane help, it's nice to be back in a challenger. We had our 09 for 10 years and was consistently in the twelves thanks to diablo
