I wouldnt expect anything more than maybe 5rwhp... They are mostly just good for adjusting your settings.

Get the handheld. It will benefit you later alot more if you keep on adding mods.

so i probably won't even notice that much of a difference? and would it shut my cel off cuz i am runnig an o/r h-pipe ,or probably just get some MIL eliminaters

The plug in wont shut off the CEL. You will need mils or a handheld for that.
