just disconnect the iac and turn the adjustment screw up a bit on your tb. I have been running that way on a 400+whp focus for years. the iac is only for when you turn on the ac it raises the idle so you dont bog it down due to increased load. so just turn up your idle manually a bit think i set mine to 1k and then when i turn on the ac it only drops to stock idle around 700 or so.. works perfect.
