Idle Concerns

When I cold start my car the car begins to idle at 900-1100 range for about 30 seconds...then it will drop to 300 for a split second (almost stalls) then increases back to about 800 where it finally normalizes. This happens every time I cold start it. The car is a supercharged 2005 GT. Any ideas why it fluctuates like this?
