NHRA National Records

Is there always a teardown involved in IHRA with the setting of a National Record? I ask because we just put a gear, converter, and tune in our '04 Corvette which will run B/PS. According to Nitro Joe's stats from last year no one else competed in this class and there is no record now either. Out of the box we hope to easily be .5 under with the potential for 1.0 with headers and more fine tuning. However, we plan for now (until we get our trailer this summer) to drive to the track.

Just curious about if a teardown is always mandatory.
