I just installed the Stillen Airbox... do I have to restart my ECU so my MAF won't be confused on why there so much air coming through than before?? When I start up my car.. the RPMS go up to 1000.. go down to like 200.. then go up to like 500.. is this 'cause i haven't reset my ecu??

The easiest way to to reset you ECU or you can drive it around for a week or 2 and it'll re-ajust itself to compensate the new air box.

The quickest way is to do the "Easy ECU Reset" or to disconnect both + and - battery terminals and touch them
togeather for around 10 seconds. Both methods work.
The pedal method will not wipe out your radio and trip
