Buick Grand National Performance Chips - Amazing Buick Grand National Chips is this a joke? i can see the reasons behind the ultrachip, i'm guessing this is more or less the same thing. NOT posting because i have 2nd thoughts on ordering a TT CHIP, none. Just wondering i was looking for the stock MPG(for whatever reason) on our hotairs. I believe is 15city/20highway,

Chips like that are usually some sort of resistor that is wired into the the IAT sensor. It tricks the computer into thinking the outside air is a different temperature than what it really is.......In short...Save your Money and buy the TT chip.
