Today I went to a Kia shop to try to discuss about the IAC valve disconnection. The "master mechanic" was pretty busy and couldn't give me proper attention, but told me to go ahead with the disconnection that I would definitivelly gain some HP. Just don't know how much. He suggested me to add a switch to the valvle, just like I wondered the other day. That's what I'm going to do, but I don't have that much skills on eletrical parts, and I think that it's not just a matter of adding a on/off switch, I'll need a relay, correct?
