My 2013 328i had the same fluctuation and I called the dealer. They said its common and normal as long as the idle does not drop to the point of killing.
Slightly off topic, but how is the AFE kit working? Are you getting a noticeable boost? I am just waiting for some mad money to come in so that I can buy the intake/scorcher combo.
