bump up your base runing airflow up 2 points and check it. Re-adjust if neccesary. Also inter values of 2 in your adaptive idle spark. In other words a max value of +2 in over-spark and -2 in the under-spark section. This will only let the computor hunt for a total of 4 degrees of timing. If not it will hunt all over the place and cause irratic idle. Also bump your idle up to 825 plus depending on the size of your cam. This should smooth out your idle a little. This is just a coulple of tips to help. Just a note do not go to high on the bass running airflow or your car will surge. Hang up on the idle to like 1500 to 2000 or higher and won't go down. Just remember to make small changes and see what happens. You might trying drilling a little bigger hole in the throttle body. That is if you have a stock throttle body. Some people say not to do this but there is a hole in the factory throttle body for a reason. That is so air can feed the idle blade position. If you have an aftermarket throttle body you can just crack the blade if you don't feel comfortable doing that. Hope this helps If you have anymore question feel free to PM me.
