I have an 04 GT 5-speed and was lookin at getting a Jet performance plug in power module, I want a plug in module over a hand held tuner.Has any one here ever used one? r they worth the $239 or just a waste of money? any advice would be apprectiated thanks

 

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.

 

ok thanks for the input guys
