My guess is that the maps you listed are just a bit too "much" for a desired idle speed of whatever is programmed. When the maps ask for too much of something but the idle speed is commanded to be lower than what is able to be maintained with the higher PW in the map the PCM constantly tries to correct itself. There's a reason the "lope" tune works the way it does......
By the way, have you adjusted any parameters that I listed above?
