performance chip fraud, Fuel Maxx

This item does nothing. i followed the instruction exactly,left the battery unhooked for 24 hours, made sure my connections were good,

and contacted customer service. They blamed me and the installation. i have been turning wrenches for years and i found no fault of mine. I ran the chip for 3 weeks still no change.In my opinion this item is a cheap fake of something that could be good. I would not recomend this item.
