Gforce performance chips Total Rip off Irvine California

Saw an ad for F150 performance chip at a site I trust, WND.com, so I ordered one. I found out later that it was actually a scam. When the "chip" came in, I opened the case and analyzed the circuit. There really was a chip but it was a 74HCT573D which is an "Octal D-type transparent latch 3-state" The chip was not actually connected to anything and wasn't powered at all. If the chip was a functional component it would have no relation to the IAT/MAF sensor circuit. I traced the actual circuit and found it to be nothing more than 5 smd resistors (6.83Kohm) connected in series for a total resistance of 34.1Kohm measured with my Fluke meter. This resistance would then be connected across the IAT/MAF sensor wires. Since the total resistance in a parallel circuit is always less than the lowest resistor, the effect of the Gforce chip is simply to reduce the sensor resistance which tricks the system into thinking the OAT is less than it really is. I didn't bother putting this part in my truck and just put it in my "lesson learned" file.
