Diablo predator issues.... So here is the issue. I had a 2005 Chrysler 300c and also a predator unit on it, on my Chrysler I could change my shift points stock,6000 and I think 6400.... On my Charger all it says is increased!!!!!!!!! Uggggg!!! Why can't I change my shift points???????

on a 2004 Pt Cruier GT Turbo H.O.. What would the top speed be with Predator installed and only a K and N drop in filter. I would like facts and not guessing please. It seems the 4 speed Automatic is really up in the RPM range, what can this motor safely hold? Does the Predator ...

I would like to konw which would be faster. A bone stock srt8 any of the car breeds. Or a modded 5.7 300c (cold air intake,diablo 93CAI tune,catch can, cat back exhaust lowerd)???
I'd like to hear feed back.
