Looking for cheap mods...
The theory of this one makes sence to me --has anyone tried this?
Have any advise for me before I do this to my 2003 GT?

Relocate IAT Sensor
In most fuel injected vehicles you will find a sensor that measures intake air temperature. You will need to refer to your factory service manual to find its location.
At any rate, it is very typical to find the IAT sensor mounted inside the intake plenum that is very often heated heavily by coolant and the cylinder head. This is fine of course, since the original equipment manufacturer designed it to work this way. However, there is a way to "trick" the engine computer into thinking that the incoming air is a little cooler than it really is, and therefore get the ECU to advance the timing a small amount and increase fuel supply at the same time.
In most mildly modified vehicles, this will create a more desirable fuel and ignition map and create a few extra horsepower.
In order to perform this mod, simply locate the sensor and remove it from the intake manifold. Fill in the hole with JB weld and proceed to remount the sensor somewhere in the intake arm. Seal everything up well, and you're done.
