I don't trust those honestly because majority dont work. As i said in the previous topic I know that their are performance modules for the g6 for the other engines... I'll double check on the 2.4 for you. They aren't things like this you hook into the car. They are modified computers (modified programming) where you take out the stock cars computer and put the modified one in place of it. generally they will increase performance as well as MPG if you take it easy with the extra power. :grinyes:
