WTF? is this for real?

[Isphius]

im sure it would work, hp numbers i dont think would be that high thou. as long as they make those right. from what im getting from the ad, it changes the output resistance of the MAF(very easy to do, which = cheap)to say its reading different temperature air, making it either advance the timing/fuel or lean the motor out a little for a better combustion, not sure exactly what that would do. its possible to burn a motor up(over lean) or cause pinging/detonation(advance timing too much) that way tho.
