Which wires on the MAF are for the IAT

For what engine liter? There's a couple of them-

1.8

It appears it doesn't have one. You were just wasting your money anyway.

Looked at it again on the 1.8 which is the impreza-it doesn't have one-like Wrench said-

It does its in the MAF, so what could i do to improve power?

No, it does not. I just looked at the PCM wiring and it does not have an IAT input.

ok, sounds good, So what shall i do to improve power

A minute ago it was mileage that you wanted to improve. Now it's power. They are completely opposite goals and if you get one, you lose the other. You have a computer controlled car. Other than keeping it well tuned, keeping the tires inflated properly and changing your driving habits, your only other option is a different vehicle but first decide whether it's power or fuel mileage that you are after.

You want a little power try this -use a 10K's ohms resistor on the coolant temperature sensor harness-There's a lot of ways to improve power but do you have the funding for it?

Sorry to confuse you, the reason i said that was because this "chip" was supposed to do both at the same time. I have already email the company for a return and refund, any car with AWD gets only moderate mileage. So im fine with getting a little worse mileage, but would like to get a little more power for take off,

I can fund certain things, but its a 1.8. only would like to do minor stuff that doesnt require a tear down and rebuild

With the 10k'ohm which i can get for a few cents, i would just connect it to the two wires correct? And will it throw my gauge off? I will donate more for everyone's help, i really appreciate it.

Dunno if it'll spit out a code but the coolant temperature will be affected there'no input signal to the computer -this trick of the resistor it will tell the computer that the engine is still cold and needs fuel-it'll be running in the open loop mode

ok, any other places i can put the resistors?

Dunno on other places-Good Luck

Hi, I was wondering if there is a wiring diagram for the MAF available? The company insists every car since the 1990's has and IAT sensor and they said its combined with my MAF

Well, they are wrong. IF it had one, it would be wired to the PCM. They don't publish a diagram for the MAF alone but here are the PCM pinouts and you will see no input for Intake air temp.

So there isnt anyway that there is any IAT?

I don't know any other languages to say that in. THERE IS NO IAT IN THAT CAR.
