The throttle cracker is trying to jack up the engine speed floor by an airflow offset. But you have a throttle body on there which may not match the IAC effective area curve built into the tune (table for that). If your porting of the BBK included filling
IAC port (never seen one, don't know if it's like the OE or not) you may need/want to enlarge the air feed hole, too small a hole limits the IAC ability to hit the goal and makes it swing wide, this can make for yo-yo action.
What is "engine speed floor"? Never heard of it!

yeah true, but there shouldnt be a need to port in that area then the throttle blade wont seat properly! just the horn part of the tb should be ported....in my opinion
