Seems like the feedback ppl claim it works.. But I dont see how?

I would never buy something like that :ermm: Looks like it manipulates the voltage sensed by the intake air temperature sensor (IAT). The computer will add or take out timing depending the temp sensed by the IAT. Although it may work to increase timing I would never trust that on my car.

noooooooooooooooo, too good to be true, it was proven to lose power and most likely lean out

Let see..first off it has a home made label on it. Secondly, what they dont show you is that its just simply two wires going in a box, and two wires coming right back out. They make these for just about every vehicle out there..It does absolutely nothing. Take the 20 dollars you were gonna spend and get some new spark plugs or something.
