Replying to Forward Pressure on Mojo 15s...

Does anyone know how to adjust it? I just got a pair of Mojo 90s with Mojo 15s shipped to me. The bindings were already mounted according to my 307mm boots. The said that I would need to take them to a tech to get the forward pressure adjusted to my boot. Would I just do this at the rental place at my mountain?

I put my boots in them a few minutes ago and they were really snug. No play at all in the binding. I want to make sure everything is correct though. I would prefer to do it myself if possible...

Thanks
