All those "chips" are just 20 cent resistors that you plug into a temperature sensor to fool your computer into thinking it is running at a different temperature. If its to good to be true, then it usualy is. By the way, if you consider this a wise idea, then do a search on the internet and you should be able find all the info you need to go down to Radio Shack and hop up your truck. Thats all these Ebay guys are doing.
