If you have an idler screw on the throttle body, unplug the iacv while the car is on, adjust the screw so that it idles around 350-400 rpm, then plug the iacv back in, turn off the car, reset your iavc at 0% in ectune, then turn the car back on, it should idle smooth, blip the throttle and see how far it drops if any, then adjust your iacv controll up and down in ectune and keep blipping the throttle until it doesnt drop anymore. Hope that helps, if you have a light flywheel, it will tend to drop more. Also you can try messing with the tipout as well.

With iacv disconnect set idle to 650 rpm for 750-800 rpm idle
