Fitech idleing issues

Been having this idleing issue for about about a month after my install and just got about 400 miles on it but It's been driving me crazy, idle keeps on going up and down from 800 which is my initial idle to 1500 back and forth and sometimes goes below that but that's after it's warm. Doesn't do it on first startup, But after I drive it then it does. Figure i drove it more for it to learn but didn't fix the idleing issue. Followed the iac step recommendations and got mine at 6, still does it. Someone mentioned lowering the idle learn max which I tried and put it down to 3 and still no go. tried calling fitech tech line several times but there's always a long wait period and when I get through they just take my number and tell me they'd call back which they never do. So much for customer service. Other than the idleing issue it takes off like a bat out hell and has great performance than the 600 cent carter carb i had on but the idleing is just blah. Just trying to get this resolved.
My setup is the basic 400hp with FCC no return line vented to the back.
