Speedo calibration

I changed my transfer case out and now my speedo is 13.5% off. It reads faster than I am actually going.
Do I want to get a nylon gear that has 13% MORE teeth or do I want a gear that has 13% LESS teeth??

Assuming that this is the gear on the cable you are replacing rather than the gear on the t.case output shaft, you want more teeth.
