I would defintely install 4:56s! I pull an enclosed aluminum car trailer with my S331SC and it is the perfect gear ratio for highway speeds. And it is a fun in town ratio, too! Had 4:30s before and it was a bit high geared for towing, but if you never tow anything they are okay.

Made the change in my 07 N/A #007-012, definitely wakes it up. You will need to reflash the ECM or install a speed sensor recalibration kit for the speedometer to read correctly. Best~
