G-Force chip
 

I just bought a chip for my Dodge Nitro ,from G-Force in California and it is snake oil,they tell you no questions asked guarantee ,60 more horse and 4-7 miles better to a gallon of gas ,turns out my car was harder on gas with it.I contacted them and the pretty much told me to get lost.So buyer beware .And they advertise on some of these forums ,so i hope i can stop someone else from being burnt.

google a search on the g-force chip,see all the bad remarks:
