Running lean at idle

Check the throttle plates and make sure they are closed at idle. Since you did a burnout I assume you buried the pedal. Have someone push the pedal to WOT and check for smooth throttle operation.
I had a carb holley VS do this every once in a while after a hard run at the track. The secondary plates were not fully closed and screwed up the idle AFR. I had to remove the carb and center the rear butterflys.
