IAT sensor only has 2 wires ,intake air temp. Maf sensor has 6, mass air flow

That is not a chip, it is a resistor in a fancy package. It cost about a dollar to make it. Jet also makes one. All it does is increase the resistance in your IAT circuit so that the PCM thinks the air coming in is colder than it actually is. Since most PCMs will add timing in colder air, you can get a bit of a perforance boost this way. The problem is, modern OBD 2 systems constantly checks itself and sensors. Since the PCM also reads a mass air flow sensor and an oxygen sensor, it eventually sees that there isn't as much air getting in as expected (since colder air is more dense) so it recalibrates the air temperture sensor thinking it is fautly. So, after a couple of days your 'chip' won't make any difference at all and in some cases it can actually cause the service engine light to come on. Also, the claims they make about these chips are unfounded and ridicuouls. Even a real chip or programmer can't expect more than a 15% gain. There is no way this IAT mod will add more than 3% and that will only be the first time you drive it. Try to get your money back and find a real chip or programmer for your car. If you are just bent on putting a resistor in your IAT wire, go get one from Radio Shack for a dollar and pocket the rest of the money.

You have to contact the mfg of that product
It won't do a thing for your vehicle
Waste of money & may do some harm
Send it back
If you have no instructions that should send up
a red flag & G Force never has them apparently
