  1. Chrysler 300 Performance Mods - Engine - 5.7L
    So I just bought myself Jron's predator (thank you by the way), I figure I'll start asking what all I should do. :D I have a CAI and Exhaust already, I figure I'll need the 180 t-stat, anything else you can think of? I'll probably just use the 91 octane tune (can't really find 93 around me).
