Here is the how to: http://stuntride.com/vbstunt/showthread.php?t=25600
+1 to what DIMA said. In addition, you can leave your stock idle at like 1200 and use the second idle to adjust. This way you'll never go below "stock" idle or have to worry about messing with it. The stock idle screw is actually an Air/Fuel adjuster. The second one is adjusting the throttle.
Basically both of these mods will help your f4i pull harder and more consistent on idle. Mine pulls like a train.
