I get idle speed trim variation of +/- 11 at times. I have chased this in the past and have given up on getting them stable as long as my fuelling is good whilst the car is moving. Seemed to me to be quite weather dependent and I have put it down to temp/humidity shifts whist the car is stationary and the oven under the hood heats up (I also have the Greddy Turbo intake which sits in the engine bay consuming the hot air).
