Insulin Pump Max Bolus.

Hey everyone! I have a minimed 630g. I have recently changed my carb ratio. Now when i try to give myself the correct ammount of insulin it can sometimes be over 25. 25 is the max my pump will let me go. So I will have to give myself 25 units and then whatever else I need. Is there a way to increase the max bolus? Is there something im missing?
