Hunting idle 4.6 2v with stage one cam

I need help I have a 97 gt with a pi motor I am using the advantage iii software. I am having the worst time trying to get my idle straight it won't stop surging. I set the idle to 900 and it still jumps around. What parameters am I supposed to adjust to fix this. I set the injector delay minus 10 from stock and shut adaptive off.
