my question is I wanted to get a the predator tuner but I still have a basically stock truck for now. Can I use like a 45 or 65hp tune from predator with stock exhaust without burning down my motor? right now I wanted slightly better fuel milage until I can get a exhaust. Does anyone have input with something like this. Also can I disable the egr with the predator tuner? I'm sorry if this has been posted before, but im new to the forums yet and still havent figured out how to browse the forums.
