If everything, including the hoses, are new and in good shape, 16 psi will be OK. The 13-psi cap was introduced in a recall due to coolant leaks causing fires (antifreeze is flammable). The turbo coolant hoses can burst (they are subject to the worst heat of all the hoses) and are a common leak point. This leaking coolant can puddle near the turbos and ignite.
