As for claims of increases in performance you should consider the source. There are gains in performance to be had, but as with all things automotive come at a cost. Increased engine power puts more strain on the engine internals. Internals that were not originally designed to cope with these increased stresses. Engine life will therefore suffer.
Increased horsepower is gained by altering the ignition timing and increasing fuel delivery(when chipping only), so obviously fuel consumption will suffer as will driveability of the vehicle especially in slow moving traffic.
As for warranty, the moment you modify an engine in the least bit the warranty is null and void. You may also want to consider the increase in insurance prmium due to driving a performance modified car.

What 2 wires are the IAT wires for 2006 kia spectra? just need to connect a performance ECU chip and don't know which 2 wires are the IAT wires.

I assume this is a chip from eBay. I suggest not going that route. All those "chips" are, are resistors that trick the car into thinking the air temperature is a certain degree, which can improve performance. However, it can affect other aspects of the car and it could cause long term damage. Also, modifying car wiring on a critical part like the IAT could cost lots if it is damaged.

Do your research. Don't rely on one manufacturer's claims. Diesel's work on precision. Any time you change something in a diesel engine it affects everything else, for example, shoving more fuel through the injectors can push them beyond the built in tolerances and lead to premature wear. One of the best authorities on diesel performance is Banks. They have been at it for a long time, GM recognized them as such in the early 80's. Trust what they tell you.If they don't offer that type of chip or performance chances are there is a reason.Hope this helps.

Glow plugs

no this will not improve the performance of your diesel, the glow plugs are used to ignite the fuel at initial start up and then they turn off.
